Oh yes, the website admin can usually find out the IP address and the domain from which the access was done.  However, it is difficult to pin-point exactly who did it unless the user has a static IP address (fixed IP address).  Usually ISPs provide you with a dynamic IP.  So its difficlut to find out who did it in your case.

Try TCPView http://www.sysinternals.com/Utilities/TcpView.html this shows all the IP addresses connected to your PC. However, it may only reach the chat provider. On my PC is shows different IP addresses for every conversation window, however, not the IP address of the person I am chatting to.\n\nI doubt whether you could locate automatically without directly asking for the persons IP address.

Type your IP in here http://www.arin.net/whois/ and have a look.  If you want to know your IP go here http://whatismyip.com/\n\nYour address, location and where you have been on the internet are a few things you can pull from an IP.

IP address are assigned to computers by their ISP, normally for a fixed period of time.  So most people won't have a permanent IP, it will change at a regular interval.  \n\nThere is no way to directly get the IP of someone given it's name or something like that.  But if you are in direct connection with them (IM, ftp, web, etc) you can get their current address using the command netstat -an from the command prompt (windows: start->run->cmd). It will list all your current connections, better to do it with no opened browser, it will be easier to identify the connection your are looking for.

dear curious boy, \nYou can get the IP address of the person you are chatting with     by propably asking he/she to go to your site or blog page.What happens here is that if you insert a small bit of html into your site then when the person acceses the page all the deatils about the person,not only the IP address but even system information and all detals about the connection and lots of other stuff gets recorded for you to come and check later .Try the link to get a better idea of what i mean .\nCheers\nSharan

They can easily find out who owns the IP address block that IP resides in, by using the regional network centres lookup databases.\n\nIf you have a small, local ISP, own the IP block yourself, or you are using the connection of somebody that owns the block, such as a company or school, this would give somebody a bit more information about where you might be.\n\nIf you are using a normal, large ISP, they can track it to the ISP only.\n\nYou cannot hide your IP address, as nothing can communicate with you if it doesn't know your address, it's where you are on the network (internet in this case).  You can use a proxy server, that would handle requests on your behalf, so the final destination doesn't see your address, but not all proxy servers are for anonymity and pass your details on, and they slow things down if you trawl the internet for free ones.

The easiest way is to connect through a proxy which will show their IP address and location not yours. Search google or yahoo for free proxy servers and you will find many.

Check the FULL headers in your "friend's" email. They will show his/her IP address. You can then trace their location using http://www.hostip.info/. I hope this helps

Find out their Ip addresses first then go to http://www.geobytes.com/IpLocator.htm and type in the Ip number in "Ip address to locate"\n\nTo find out their Ip address, you can use Sitemeter on your xanga or website if you have one. Another way is (if they cooperate) asking them to go to http://www.whatismyip.com and to tell you their Ip number

if you check the IP address, you should be able to track it down.
