Suppose that are registered with an Internet Service Provider (ISP) if you are still relatively new, these are Internet-order. Changed over time, we began to understand that is not expressed on all the promises in the early stages. For some reason, their service is not what you want. Or worse, what if your ISP is terminating shot so that even without a host.

Survived, and with the emergency plan right, so can you. The transition to a new ISP / Web hosting provider or who is not as scary as you might think.

Probably the most important thing you must understand and implement this moment is the backup. Data backup ensures that no matter what happens on your site or dataYour Web server space is always a current up-to-date copies of files available in case of emergency, and believe me when I say that emergencies happen.

Britain is in the Broadband Slow Lane

A recent study of broadband users has revealed that 44 percent of the customers are always only half the speed promised by your ISP for download 's. The study, a survey of 43,000 people, 61% of them chose their ISP because of the speed with which they were promised. The problem is caused by ISP 's advertising for the maximum download speed possible, but in most cases, these speeds are only in selected areas.

The telephone network is Britishresponsible for the construction of homes of millions of broadband users. Most of this is to use the traditional copper wires that were not originally designed to cope with the transfer of data is carried out at high speed. Britain is seriously than the rest of the world when it comes to broadband speed. BT is trying to invest 10 billion euros to upgrade the network in Britain, but it seems as if it may take many years to follow the leaders of the world, like Japan and couldFrance.

We are rapidly becoming a nation of addicts of downloads, with the number one choice to download music launch games, movies, and follow pod. With the growing number of people, the increasing amount of data downloaded, the speed is always the most important factor when choosing your ISP.

Rob Barnes, head of broadband is a price comparison site said: "As most are only half as fast to get registered, a typical film of 500 MB can store up tofour hours to download, instead of 60-90 minutes. If you have downloaded a podcast of 50MB, is expected to be discharged within 10 minutes if you use an 8-MB line at speeds below this could wait until half an hour.

"When the download culture to grow further, the speed of broadband is most important. Fortunately, OFCOM has decided to release six of the largest ISPs in hand, watching the speed that advertising, and what people actually .From this consultation, the supplier must be kept clear and transparent advice on people speed give to be able to reach, perhaps an examination of how O2 broadband, as part of the process when I am on a new contract. In the meantime, I'd be all those who download large files such as films, wants to opt for a combination of 16 MB or more with unlimited download capabilities to recommend. Suppliers, such as broadband, Virgin Media and Sky Broadband offer this. "

The best way to trace an e-mail

It is quite common, a disturbing, unwarranted and unworthy of e-mail message from an individual and the people who do not even know you. Sometimes you get to see them and ignore them, after a reading from the front row. Other times they are simply annoying, and then delete it immediately cursing the whole time. Others have the heart to get the guilty, but not both will have the ability and the know-how to maintain such an individual. Worse still, if you have received a greatthreatening to send a message that in fact a shiver down my spine. When push comes to shove, to save lives, it would be to get help, how to get an email address that person so that he can meet with the authorities and pay for all the emotional trauma that he or she has caused lane.

Previously it was difficult to find the person who started mostly because he has not received any advanced technology on-line, these people. But as is currently seeking new and reverse-mail isa tool developed for the person, collecting less information, in fact, the lowest IP address of the person. As for the reverse lookup e-mail I can not tell you the details you may require, it will certainly provide more conclusive pit the boy, even if it was hidden deep in the oasis in the Sahara desert. This service is still quite new and still in further development, but overall it was shown that both the success andflexible.

Investigation of the guilty person go to find the ISP address, was the medium used to search for these people nub. But after a while ', and many failed attempts, the method has been used with no replacement until the introduction of reverse lookup e-mail waiting. The problem with the research provider was that it was too long to find the person and the person has long had almost caught up with a new ISP address was gone. The disadvantage of otherwas that it was necessary to pay suppliers necessary for the long term, to solve the case was too expensive. Therefore the software that was used is inadequate and inflexible, unable to stay with a very deep research and powerful ISP compatible. We can say with certainty that it was the reverse lookup e-mail is a kind of savior, to say the least.

How does the opposite, it's big and powerful, armed with more powerful software, an e-mail record is now so simple that kidscaught in the process I've always wondered what really really happened. The resources you can use the lower end of the study go to the entire conspiracy and mail-out as soon as possible. If you are so anxious to get the bad out of the back, it's time to come to us for the best weapon to eradicate them.

Voice of an ISP Port25 Block Using a Modified config sendmail

When you try to send your newsletter from your home computer with a desktop mailer Studio mailbox, you may be frustrated by your ISP. ISP of the majority, to limit the number of e-mail you can send in a day or even every hour. The solution is always a hosting account with POP / SMTP to receive the privileges and use this server to send e-mail. However, the large ISPs are now blocking access to port 25, the door to transfer electronic mail, unless your server.In essence, they say that you must use our server to send mail, and we can only so many e-mails a day. Sometimes you can use your Internet Service Provider (not AOL!) Employment, and can stop, usually only if you agree to receive a corporate account, rather than a residential account Remove. But what happens if you do not have this possibility?

If the remote server based on Linux, and you have root access, you can actually change the configuration of sendmail to listen to the mail to more than onePort. Sendmail is the default MTA (Mail Transport Agent) on Linux web sites in recent days. There are two ways to do this, depending on the configuration of sendmail.

The preferred method is the file sendmail M4 configuration file using a high level. The server must have the sendmail-cf package installed. If you have an m4 file is in / etc or / etc / mail and be called sendmail.mc. Edit the sendmail.mc file and locate the following line:

DAEMON_OPTIONS ( `Port = smtp,Name = MTA ') dnl

Insert a new line, and add

DAEMON_OPTIONS ( `Port = 9925, Name = MTA1 ') dnl

Save the file and compile with

m4 sendmail.mc> / etc / sendmail.cf

Now you have two demons Mailer, one of them to Port25 and one on Port9925. You can change the port M4 files to a port which is free and available through the firewall.

You can also directly edit the sendmail.cf file, but this is dangerous, even for experts. And if your web host has aPanel for the addition of new domains, any changes made to. CF can be overwritten. Here, after full disclosure, is how you do it.

Edit the sendmail.cf file with vi or emacs. Search for "daemonport. You see a line like:

O DaemonPortOptions = Name = MTA

Comment on this with # and add these two lines instead:

O DaemonPortOptions = Name = MTA, Port = 25
O DaemonPortOptions = Name = MTA1, port = 9925

Save the file and use sendmail. restart or/ Etc / rc.d / init.d / sendmail restart

You can check if it works (and even if your Port25 is blocked) via Telnet.

Open a command prompt and type: "telnet servername 25" (user of the server) instead of the server name. If you connect a connection, you reach the sendmail greeting and you are not stuck on Port25. Enter "quit" exit

Telnet on port 9925 again You should now see the SMTP greeting banner. Congratulations, you can bypass the blocking ISP, but itnot finished yet. Now go into your email program and the SMTP port to 9925 In Outlook Express this card can Account Properties Advanced page to be found. I hope that if you can use an autoresponder, you, the port and server, you can define send e-mail.

It 'also possible, if not something similar be hosted on a Windows server, but in reality is more complex and is beyond the scope of this article.

How to connect multiple computers to a broadband Internet connection

Broadband or high-speed Internet connection is what many users are currently in use in their home. Along with high-speed Internet, many users can also use a router to connect multiple computers to the Internet. This document describes how to use a router to connect multiple computers. Easier to understand, I will use when you live as a comparison to how the computer is connected to the Internet.

What is an IP address?

IP addresses are a series ofFigures nnn.nnn.nnn.nnn in the form: nnn is the start of a three-digit number. An IP address is unique for a single computer in a network, just like at home, has a unique address. Provided a connection to the Internet, an IP address from your Internet service provider (ISP's). In some cases, your ISP may have more than one IP address, which you can connect to multiple computers. As we shall see later, however, you can connect to multiple computersa single IP address.

Connecting a single computer

Connecting a single computer to your high-speed Internet is very easy to do. Simply connect a network cable to the modem and then into the network card in your computer. The computer will be assigned an IP address from your ISP. For example, if your ISP assigns you the IP address 24.24.50.17, then the IP address of the computer.

If you have a request to a server, for exampleWeb page knows the web server, the IP address that made the request. The information is then sent via the Internet and back to your computer. This is similar, if someone sends mail to your home. The address on the e-mail can be delivered at home and not elsewhere.

Multiple computers

How can connect multiple computers, if only one address is assigned? If you know an application of a web page, how it works, what kind of computer is necessaryPage? Let our home analogy a step further. Suppose, instead of living in a house that you live in an apartment. If someone sends you e-mail, not only address but also an apartment. This figure is inside your house apartment and each apartment has its own number. Similarly, multiple computers can connect to the Internet when they are there own local IP address. This can be managed by a router.

A router is a piece of hardware,connects directly to the modem. Each computer is then connected to the router instead of the modem. Now, instead of the computer with the IP address from the provider, the router is now assigned the IP address provided. This is comparable to the router via the apartment.

The beauty of a router is that you can assign your own local IP addresses. If you get a computer to the router is now one of the router's IP address, similarly classified, as the individual Apartment has its own number. If we now make a request to a Web page, the request is sent to the provider the same address, but this time is to assign to the router. If the Web page is returned, the router receives the request and sends it locally on your computer, the requested page.

The router also has its own local address, which is the local IP addresses of computers alone. So now the router has assigned more than two addresses: one for an external one if your> ISP, and one local, who has made available. This allows the router to connect to the Internet and local network.

Note: The address 192.168.xxx.xxx are special IP addresses for local area networks (LANs) are reserved.

Managing a Web or FTP server on the network

Let's take a look at this scenario. You have a router that connects multiple computers to the Internet. But now you want to create an FTP or Web server. No problem. The installer software is needed onComputers on the network, "said someone outside the network, the local IP address of the FTP server and try to get in touch. Then he discovered that he can not connect. Why? Like something someone just list Please include your home and no address.

The IP address assigned to your computer on the network. You can connect with other computers on the network, but not from the Internet. You need your ISP assigned IP address(assigned to the router) to have someone from the Internet to connect to FTP server. The problem is that the router assigns the IP address and the computer, and as an IP address must be unique, as two computers can share the same IP? The answer: you can not, but it is not.

Routers are able to provide information on a port to a specific computer to be transmitted. A port is a channel numbered according to which data can be sent to a network. You can not physically see, as it is aChannel length of the virtual network used for sending / receiving data. For FTP servers the default port is 21, but another port can be used.

Open the router configuration and look for the option of port forwarding. Enter the internal IP address of the FTP server and the port number and then save the information. Now, if a user tries to access the FTP site must rely on the ISP assigned IP address for the router. The router will then establish that the data senton port 21 and then forward it automatically to the FTP server. A web server is setup the same way, but the default port is in Rule 80;

Note: By default, a router dynamically assign IP addresses to computers connected to it. This means that the first computer is connected to the router for the first available IP address received, and the next will get the second, and so on. If you assign an FTP server for management, may be easier to have a static IP address on your computer in order to ensurethe FTP server is always the same IP address.

This article describes how to connect one or more computers to an Internet connection. It 'important to remember the following:

If you have a computer connected directly to the modem, so that the computers are assigned the IP address from your ISP.
When you use a router that the router assigned the IP address from your ISP. Every computer connected to the router receives a local addressRouter.
Router, the IP address of the provider and a local IP address. This allows you to connect to the Internet and network connections.
When you set up a computer as FTP, Web or communicate with other servers on the Internet, it is important to use the IP address of the router to access the server. You must then send the necessary port on the server.

You Can Get Around ISP Shaping and Still Watch TV Online

Throughout the world, ISPs have found that a Bit Torrent taking toll on their networks and have begun to restrict traffic, especially during peak hours. What does this mean for the average user that is used to download torrents from slow or even worse, all during peak hours. It also means that may not be able to see your favorite TV show, if you want. TV There is an alternative: on-line through streaming technology.

What is the design,exactly?

Shaping, in short, is the limitation of certain traffic. This can occur during peak hours or all the time. How do ISPs will depend on their technical, but focus only on items that share the load on their network and Bit Torrent is now high on the list, since they share the load on networks. For example, Comcast in the United States still allows anonymous users to download shows, but do not allow seeding. Whereas the AtlanticLimited bandwidth broadband effectively slowing Download Bit Torrent. They are good in their own right to do so, because it is supported for all users during peak hours, in particular, were able to restrict certain traffic.

Ignore how do you move?

There are several ways to work around the design, actually. The first option is to encrypt the torrents to trick the ISP. Cluey takes to do this, but it is possible. The other option is to find aalternative way to view data on your computer.

Streaming view of the provider and because like any other.

Without being too technical, on an ISP streaming video looks like normal traffic. Use the computer language, known as Real Time Streaming Protocol (RTSP) is very similar to the HTTP protocol, using the majority of websites in one form or another. Why is it so similar, is not to focus on how Bit Torrent. For all intensive purposes, streaminginvisible to the ISP, and then fly under the radar.

What are the disadvantages?

There are some drawbacks with streaming, because it is an alternative technology. At peak hours, at the same time, ISPs are shaping their traffic is crazy, it is possible that the picture is jerky or low quality. During peak hours this should not be a problem.

How do I use to watch streaming TV online?

There are two ways that you can use for streamingWatch online TV show. The first is on the website of the network, if you're in town for the show. The other way is for a client, which is actually very similar to use with a client for download via Bit Torrent. After the client on your computer, you can change the channel you want to choose to see. The big advantage of going with a client is that you can watch TV programs on-line and in real time, and are not limited to the country of origin. Be careful, though, there are two types ofCustomer for approval of the methods used and torrenting is a peer-to-peer TV or P2PTV known, and the other is a client streaming. He who care for them because it is such, it receives about the project.

Only demographics, which are unwantedDial-up customers using today, making it almost impossible for them to advertise their inventory than they want to sell.

However, it differs considerably from country to country. In America, for example, free ISPs such as Juno and NetZero still holding market share, particularly thanks to its vast geographical distances between cities so that broadband is not practical in some places. AOL dial-up, although not free and not very good, even surprisingly dominantthe American market.

Many European countries, on the other side are in the middle of the broadband price war with some telecom providers like TalkTalk UK offers free broadband phone service as part of its strategy. This broadband is often of dubious quality and customer needs, subscribe to phone service with the provider, but in the hands of others, is not an intentional feature any advertising or paralysis of the services in a way that many ISP dialupdid.

However, in future we could in the direction of a return to free Internet service provider, with the advent of wireless networks. By sending radio signals, essentially free, except the cost of equipment, and as wireless technology improves, it will be cheaper, entire towns and villages, with wireless broadband coverage. E 'possible in the future, subscription-based providers might well die, to be replaced by local governments andDealing with the authorities, Internet access, in the same way as water and waste disposal.

FurtherAdvantage of this type of connection is the fact that most monitoring companies use this technology routinely query the connection to ensure that it is active. One answer is an event triggered idle (status of alert), if not one, but you will be notified. This lets you know that the Internet connection is not working properly.

(For those without a wired broadband Internet via satellite), there are promising developments in this area. Onceis completed, these systems work exactly as described above, but working with your satellite provider, rather than through a traditional ISP. The future of security at home is very bright.

With the rise in the number of monitoring capabilities in the course, new technologies to market and other configuration options, has never been a better time to exploit the game with an alarm system home. With a little 'research you may find that one easily with yourRequirements, if you have a phone or not.

Keep your Internet connection to DSL or Cable Service Troubleshooting

One of the most common problems among internet users is testing their
Internet to identify the problem. There are a large number of Internet users who use DSL and cable modem services.

Set your connection, like your ISP (Internet Service Provider), a commission. Sometimes it works, for many reasons.

Their service is not ready, the hardware is connected properly, or problems with your ISP.

Regardless of the cause ofProblem, perhaps, there are some diagnostic tools you can use in Windows XP to identify the problem.

If you are not exactly in the diagnosis, there will be a good idea, anyway.

Before coming to the diagnostic tools that allow us to discuss what is involved in a connection to the Internet.

The information travels over the Internet to your computer via the service provider of Internet services. This will be installed by a high-speed modem has a network card in your computer has.

YourComputer called the host, give your service
The IP address of DNS server, and you will receive your login and password. This is everything you want from your ISP.

Sometimes, the Internet connection fails, and if you want to find
problem. You can solve the problem, or at least get a little '
About the problem, consult your ISP for help.

We begin with access to the command prompt, then clicking on:

Start Menu, Programs,Accessories, then Command Prompt. Window
when you open the command at the command prompt.

At the command prompt, command prompt, type: IPCONFIG. This command gives you the active network connection on your computer. Here's an example:

PPP adapter Copy:

Connection-specific DNS Suffix. :

IP address. . . . . . . . . . . . : 68.239.158.45

Subnet Mask. . . . . . . . . . . : 255.255.255.255

Default Gateway. . . . . . . . . : 68.239.158.45

TheThis edition was created when I run the ipconfig command on my computer running Windows XP and a DSL connection. The IP address of my computer from the address assigned by your ISP.

Please note, you can create an option to add this command to get detailed information about the connection. The output when I ran the same command with the
Option "All".

Ipconfig / all

PPP adapter Copy:

Connection-specific DNS Suffix. :

Description. .. . . . . . . . . : WAN (PPP / SLIP) Interface

Physical Address. . . . . . . . . : 00-53-45-00-00-00

DHCP enabled. . . . . . . . . . . : No

IP address. . . . . . . . . . . . : 68.239.158.45

Subnet Mask. . . . . . . . . . . : 255.255.255.255

Default Gateway. . . . . . . . . : 68.239.158.45

DNS server. . . . . . . . . . . : 151.198.0.39
151.197.0.39
NetBIOS over TCP / IP. . . . . . . . : Disabled

Note now that the output includes thePhysical address of the network interface card installed in my computer. In addition, you will see the DNS IP addresses. With the information above, I have no problems.

Should I keep my DSL connection and ran the command again, this is the new record:

Ethernet LAN:

Connection-specific DNS Suffix. :

IP address. . . . . . . . . . . . : 192.168.0.1

Subnet Mask. . . . . . . . . . . : 255.255.255.0

Default Gateway. . . . . .. . . :

Note: In this case, when I disconnected my connection, do not get a DNS server. This shows that I'm not connected to the Internet.

Also note the IP address starts with 192.168, the address of default, if your computer is not connected to the Internet.

Another command is the ping command. Examine to determine if a computer is connected to the network and wish to communicate, whether intranet,
or the Internet.

Once you start, youa packet to the computer specified and gives the travel time to the package. This is a one-out, when I tried to ping http://www.yahoo.com:

C:> ping http://www.yahoo.com

Ping Www.yahoo.akadns.net [216.109.118.66] with 32 bytes of data:

Reply from 216.109.118.66: bytes = 32 time = 35 ms TTL = 55

Reply from 216.109.118.66: bytes = 32 time = 39MS TTL = 55

Ping statistics for 216.109.118.66:

Packets: Sent = 4, Received = 4, Lost = 0 (0%Loss)

Approximate round trip times in milliseconds:

Minimum = 35ms, Maximum = 39MS, Average = 38ms.

This shows that the host could be achieved, and connected to the Internet.

A command is very important Nslookup. So that you can verify that DNS (Domain Name Server) correct. The function of the DNS server IP addresses of domain names of computers on the network to translate. Here's an example:

C:> nslookup http://www.yahoo.com

Serverhome5.bellatlantic.net

Address: 151.198.0.39

Non-authoritative answer:

Name: http://www.yahoo.akadns.net

Addresses: 216.109.118.67

Alias: http://www.yahoo.com

Then, enter the name Nslookup, enter IP addresses and vice versa.

In summary, there are several commands in Windows XP, with the three above commands, but it should be a good idea for problems with your Internet connection. You can find where the problem occurs. IsYour car or Internet service provider.

Thank you,

Is the IP address Reveal my Physical Location?

"Someone may have the position of a user (name, address, etc.) simply by providing their e-mail or an IP address? The reason I ask my kids some games online and these sites sometimes have a chat area, where players can talk to each other during the game. I tracked my children in some way? "

Are you invisible online?

It 'true that your IP address is not a secret. This is an important part of Internet communication protocols to send your IP address when you connect to another site, Request a web page, chat, an online game, etc. Without your IP address, the computer at the other end does not know where to send the reply.

But this does not mean that offenders can find your house if they know your IP address. Every time you go online (if you have dialup) or each time you restart your computer (if you have cable or DSL) you will be assigned an IP address assigned randomly selected from a pool of IP for your Internet Service Provider (ISP).
Your WHOIS> ISP

A person may also be able to get a general idea of geographical position, for example, through your IP address, doing a search on the WHOIS database, but only that they meet the physical location of the provider - not your address.

And if you have a large regional or national ISP, shows IP Lookup, probably nothing interesting. For example, if you're an AOL subscriber, your IP address to find the location of Dulles, Virginia show - regardlesswhere you live.
If the bill is A Knockin '

Of course, there is an exception to the rule. If Joe or Jane User calls your ISP and wants to know who is with a certain IP address last Tuesday, providers say their disappearance. But if an officer of the law hands your ISP a court order provides that the information disclosed must do so. The log provider will be able to identify with the customer on a specific IP address to a specific date and time, and wasmust demonstrate that information, if a court has found probable cause for the fact that a crime was committed by that person.

But for the true paranoid (or the criminal inclined) there are ways to surf the Internet anonymously. The Anonymizer service will act as a proxy between you and your ISP and say that the data is not mentioned because they save it.
What about e-mail?

The concepts for your e-mail. The part after the "@"Character ISP 's domain name. And to determine, given the domain name can be the physical location of the provider ', but nothing personal identification for the users e-mail without a warrant.

Web-based email accounts are not truly anonymous, either. Even if you do not use your real name when registering, they can monitor your IP address and trace through your ISP, if necessary.
Other considerations

It 'much more likely to be revealed to you or your childrenTheir physical location the old fashioned way - by just blurting it out. The children who are remembered, or chat online to play often because they should never reveal personal information including their name, phone number or address.

Oh, and if you have any spyware or virus on your system, all bets are off. These things are intended to violate your privacy.

Part I - Tier 1 and Tier 2 Bandwidth Provider - What to choose for a solution of the bandwidth

I should have said "it depends".

The first question you should ask is: "How is the Internet bandwidth will be used?" Let's say the company has a very large clientele, and that your company has hosted a website, the provided application services for customers. Would in this case, you probably want to use the same ISP (probability that an animal 1) that your client uses. In most cases, will provide the fastest (in terms of Internet router hops) from PC to your customers for your businessMega-site with your Internet provider IP network - because your customers do not cross-package public peering points (NAPs). (I have only this offer is unlikely, for example, to illustrate a point)

Another scenario is more likely that your company has several remote sites, who wanted to connect via VPN. In an ideal world you want to install remote access to the Internet from ISP site. This is again so that the number of router hops between theRemote places and the seat of the site on the Internet, will be minimized through points of peering out, and latency is minimized. If the branches are distributed in the United States, you must think of a Tier 1 ISP service for all your remote controls. If the hands of others, remote sites at the regional level, a strong regional level 2 ISP can offer better access, lower prices and better peering with other regional providers.

Of course, Another important aspect is the flexibility of the Internet service provider "last mile" to provide the connectivity options. Can the ISP to grow with you? You can start with a single T1 Internet connection, which grows to two or three T1s in a Multilink PPP. In which the ISP can take from there? It is an optical fiber networks in your building (in support of a DS3 or OC3 or Packet over SONET) an option? Is redundant connections with different fibers forwarded an option? How far is your company fromPoint> provider of Presence (POP)? If the provider of access to the fiber in your area, or would be installed?

I hope I have started to make a case that the bandwidth and price are not the only things to consider when choosing an ISP.

Note that if you MPLS connectivity to the sites of other companies to use to connect to the Internet, QoS is not really come into play. An SLA on the other hand, is always a good thing to have - especially if you useMission-critical applications for your company (or client) of your company. And probably not a bad idea to get the financial health of the provider as well.

All that said ... Here's a simple reason for the selection of a Tier-1.

Tthe simple answer is that the Tier 1 providers Pier privately with each other and how to expand their connections needed to support its customers and to transfer Internet traffic that are mutually reinforcing. Tier 2 and still earn belowBandwidth of the Tier 1 providers to traffic to and from the main providers of Internet backbone, the Tier-1 represent the movement.

In essence, hops, and have less potential bottlenecks, the better the solution provider is your world and the largest of the spine and the connections under all Internet service providers, the better the communication and performance expected power.

Now, of course .... this is what I do need your business 'and' for?

Tier 2 suppliers cangood service, but if you want to create a multi-WAN site and all locations are given in the same Tier 1 service area, its hard to see how it is able to obtain a more reliable would be a network provided by an animal -1. Any failure would have been maintained by a supplier ... It's really great the fall in level 2 vendor: packages will be riding someone else's glass or copper for the last mile of the journey. What happens, usually where 90% + of problems with an MPLS configurationJump out ... between the environment and CO CPE at the sites.

The bottom line .... Much depends on what type of service you want and where.

To help you walk through a decision on a solution of bandwidth ... I suggest taking advantage of the free assistance available from DS3-Bandwidth.com.

Internet Security and VPN Network Design

Overview

This article describes some key technical concepts, with a VPN connection. A Virtual Private Network (VPN) integration of remote workers, companies with subsidiaries and business partners over the Internet and keeps the encrypted tunnel between sites. An Access-VPN is used for remote users to connect to the corporate network. The remote workstation or laptop will go into a circuit of access, such as cable, DSL, or use local wireless Internet Service Provider(ISP). With a client-initiated model, the software on the remote workstation builds an encrypted tunnel from the laptop to the Internet service provider to use IPSec, Layer 2 Tunneling Protocol (L2TP) or Point to Point Tunneling Protocol (PPTP). The user must authenticate as an authorized user VPN with your ISP. Once completed, the ISP builds an encrypted tunnel to the corporate router or VPN concentrator. TACACS, RADIUS, or Windows servers, remote users authenticate asEmployee is allowed access to the corporate network. This term, it must authenticate the remote user, then the local domain Windows servers, Unix servers or mainframe hosts, depending on where you network account. The ISP has launched model is less secure than client-initiated model, because the encrypted tunnel from your Internet service provider to the enterprise VPN concentrator or VPN router built only. In addition to the secure VPN tunnel is being built with L2TP or L2F.

The ExtranetPartners will combine the company VPN to a corporate network by establishing a secure VPN connection from the business to the enterprise router VPN router or concentrator. Used, the specific tunneling protocol depends on whether it is a router or dial-up remotely. The options for an extranet VPN routers are connected IPsec or Generic Routing Encapsulation (GRE). Extranet use dialup connections, L2TP or L2F. The Intranet VPN will connect companies with offices in connection with asecure connection with the same process as the GRE or IPSec tunneling protocols. It 'important to note that what is VPN makes it very convenient and efficient, is using existing Internet companies to carry traffic. Consequently, many companies are choosing the IPSec security protocol of choice to ensure that the information will travel safely between the router or laptop computer and router. It IPSec 3DES encryption, IKE key exchange, authentication and includedMD5 authentication, route, authentication, authorization and provide confidentiality.

Internet Protocol Security (IPSec)

IPSec operation is significant because it uses a security protocol is dominant today, with the virtual private network. IPSec is specified by RFC 2401 and developed as an open standard for the secure transport of IP over the Internet public. The structure of the package consists of a header containing IP / IPSec Header / Encapsulating Security Payload.IPSec provides authentication and 3DES encryption with MD5. In addition, there is the Internet Key Exchange (IKE) and ISAKMP, the distribution of secret keys between IPSec peers automatic devices (routers and concentrators) for sale. These protocols are necessary for the negotiation of one or two security associations so. IPSec security association is an encryption algorithm (3DES), the hash algorithm (MD5) and a method of authentication (MD5) together. To use the access VPN implementations3 security associations (SA) for each port (transmit, receive and IKE). A corporate network with many devices IPSec peer is a trusted organization to be used for the scalability of authentication, instead of IKE / Pre-Shared Keys.

Access VPN Design

The VPN is a lever on the availability and low cost of Internet connectivity for the company central office with WiFi, DSL and cable access circuits connecting the local Internet Service Provider. The main problem is that companies should be protected as they travel over the Internet from laptops telecommuters basic office of the company. A client will be launchedused to build an IPSec tunnel from each laptop client, which ends in a VPN concentrator. Each laptop is configured with the VPN client software to run on Windows. The teleworker must authenticate before dialing a local access number, and authentication with the ISP. The RADIUS server for any dial-up as teleworkers authorized. Once this is complete, the remote to authenticate and authorize users with Windows, Solaris, mainframe or serverRestart all applications. There are two VPN concentrators, which are configured for failover with Virtual Routing Redundancy Protocol (VRRP) one of them should not be available.

Any merger between the router and firewall external links. Prevent a new feature with the VPN concentrators denial of service (DOS) attacks by external hackers could affect the availability of the network. Firewalls are configured for the IP address source and destination are allowed, theeach teleworker assigned by a default interval. How good is each application of the protocol and ports on the firewall, you need permission.

Extranet VPN Design

VPN Extranet is designed to allow secure connection from any commercial office central office. Safety is the primary goal, as the Internet to carry all the traffic used by each trading partner. This is a circuit connection from anyBusiness, which is a VPN router at the center of the company to finish for the office. Each firm and its peer VPN router at headquarters to use a router with a VPN module. The module provides IPSec encryption hardware and high-speed packet before being transported over the Internet. Peer VPN router of the company are dual-core home office several multilayer switches for the left diversity should not be one of the links will be available. It is important that the movement ofa business does not stop at another sales office. The switches are among the internal and external firewalls to connect public servers and external DNS server is used removed. This is not a safety issue, as external firewall to filter Internet traffic.

In addition, you can filter all network switches will be implemented also to avoid the routes from being advertised or failures to have business relations with the exploited toKern Office multilayer switch. Separate VLAN for each network switch will be assigned to each company in order to improve the security and traffic segmentation subnet. Level 2 external firewall will examine each packet and to allow companies to source and destination IP address, application and protocol ports they need. Meetings with business partners need to authenticate with the RADIUS server. Once completed, it will be the authentication of Windows, Solaris, orMainframe computer before all applications.

Free ISP?

Yes, there is no such thing as a free Internet service provider or Internet service provider. An Internet Service Provider is a company, access to the Internet, usually for a small fee. However, you may be surprised that St. Free ISP 'If you're wondering if I refer to disks you receive in the mail that will offer Internet access free for 30 days, think again. The ISP' s, I speak not only offers a free trial version.

So how> ISP 's to offer free Internet access? The answer to this is not surprising. In fact, advertising is the funding source behind many free products. For example, you can use many sites offer free MP3 downloads. But coming just as the free ISP, these pages with a large number of pop-up ads. In reality, these pop-up can be so many available on free internet access through the Internet service provider can be a real nuisance. You can even stallThe computer and make it difficult and frustrating to navigate the Internet.

In addition, that offer free ISP 's do not offer access to the internet or internet access in your area. If there is a dial-up number in your area, you have to go without it in certain circumstances. These providers can also use the amount of time you spend surfing the net. The height of the features that commercial ISP 's can be lost when it is released with a provider of Internet services. Most Internet service providers for their servicesagain and again, with new features. This is not the case of providers that offer free internet service. Free ISP 's can also be a bad connection interruptions that s. Business ISP '

If you're an ISP, one step away from a free ISP 's, the answer might be, in front of you. You see, many ISPs that offer free services to the Internet can also be a prize package for a low cost. InIndeed, it may be a way, with free Internet access for Internet service providers to attract customers. Once a customer sees that they can enjoy with your ISP, they decide to purchase unlimited access to them rather than their competitors.

Before accepting the terms and conditions of the provider, always make sure to read and understand everything. When you declare free access to the Internet to search for particular attention to your ISP is really with the freeInternet access is expected to have. They also want to make sure you know how much of your time with the Internet is limited, if this is the case. Want to search for any additional costs or long distance charges that may be your ISP.

ISP Interconnection

ISP Interconnection

Just as their customers pay them for Internet access, ISPs themselves pay upstream ISPs for Internet access.
In the simplest case, a single connection is established to an upstream ISP and is used to transmit data to or from areas of the Internet beyond the home network; this mode of interconnection is often cascaded multiple times until reaching a Tier 1 carrier.

In reality, the situation is often more complex. ISPs with more than one point of presence (PoP) may have separate connections to an upstream ISP at multiple PoPs, or they may be customers of multiple upstream ISPs and may have connections to each one of them at one or more point of presence.

[edit] Peering

Main article: Peering
ISPs may engage in peering, where multiple ISPs interconnect at peering points or Internet exchange points (IXs), allowing routing of data between each network, without charging one another for the data transmitted - data that would otherwise have passed through a third upstream ISP, incurring charges from the upstream ISP.

ISPs requiring no upstream and having only customers (end customers and/or peer ISPs) are called Tier 1 ISPs.

Network hardware, software and specifications, as well as the expertise of network management personnel are important in ensuring that data follows the most efficient route, and upstream connections work reliably. A tradeoff between cost and efficiency is possible.

[edit] Virtual ISP
A Virtual ISP (vISP) is an operation which purchases services from another ISP (sometimes called a "wholesale ISP" in this context[1][2]) which allow the vISP's customers to access the Internet via one or more points of presence (PoPs) owned and operated by the wholesale ISP.

There are various models for the delivery of this type of service. The vISP can provide network (internet) access to end users via access nodes owned by the wholesale ISP (e.g. dial-up modem PoPs or DSLAMs installed in telephone exchanges), routing network traffic itself to its destination.

[citation needed] In another model, the vISP does not route any end user traffic, and needs only to provide AAA (Authentication, Authorization and Accounting) functions, and may additionally provide "value-add" services like email or web hosting using its own facilities.[citation needed]
The service provided by a wholesale ISP in a vISP model is distinct from that of an upstream ISP, in that a vISP in most cases only provides a means of connection for the customer with an actual backbone/upstream ISP handling the routing and transmission of data, while a wholesale ISP handles both in one case; they may however be one and the same company or strongly affiliated, with the vISP being the customer front-end, while the actual backbone provider is a subsidiary or affiliation.

A vISP can also refer to a completely automated white label service offered to anyone at no cost or for a minimal set-up fee. The actual ISP providing the service generates revenue from customers using the service, and may also share a percentage of that revenue with the owner of the vISP.

[citation needed] All technical aspects are dealt with by the ISP providing the infrastructure, thus leaving the owner of the vISP operation with the task of promoting the service. This sort of service is however declining due to the popularity of unmetered internet access also known as flatrate.[citation needed]

[edit] Free ISP
Free ISPs are Internet Service Providers (ISPs) which provide service free of charge. Many free ISPs display advertisements while the user is connected; like commercial television, in a sense they are selling the users' attention to the advertiser.

Other free ISPs, often called freenets, are run on a nonprofit basis, usually with volunteer staff. There are also free shell providers and free web hosts.

ISP (disambiguation).

An Internet service provider (ISP, also called Internet access provider or IAP) is a company which offers their customers access to the Internet. The ISP connects to its customers using a data transmission technology appropriate for delivering Internet Protocol datagrams, such as dial-up, DSL, cable modem or dedicated high-speed interconnects.

ISPs may provide Internet e-mail accounts to users which allow them to communicate with one another by sending and receiving electronic messages through their ISPs' servers.
ISPs may provide other services such as remotely storing data files on behalf of their customers, as well as other services unique to each particular ISP.
