"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.
