Assuming it is a static IP (always on type of connection), it would be possible to attack a computer or network of computers.  This of course assumes malicious intent.  However, having a firewall in place provides protection from such attacks.

Check all your credit cards and your accounts.  Check your credit rating.  Advise your bank about what is happening.  Respond to all these offers by letting them know that there is no such person at this address and that someone is using your address without your permission.

Just use your Yahoo "spam" key. It will block that IP from sending to you again and reports it to Yahoo. Many complaints for the same offending IP from other users and Yahoo blocks them and in some cases reports them to proper authority's.

Every computer on the internet automatically gets an IP-address (probably from your provider). Based on this IP-address websites can locate any computer that connects to them (down to a broad region).\n\nYou can not change this IP address or location information on your computer.\n\nYou can bypass this check by routing your web visits through another computer in the USA. Some websites  can do this for you. You should search for 'anonymizer' in google.\n\nThis page has a collection of them: (take one from USA off course): http://www.proxys4all.com/web-based.shtml

Your IP address is always going to be visible and/or logged by any system you connect to. Just because someone says "I have your IP address" it doesn't mean your system is compromised. You can even view your IP address at sites such as www.myip.dk. It is very easily obtainable when browsing the internet. If you do not want sites to be able to access it when you browse them, use a proxy server, eg. www.phpproxy.com. If people are obtaining your IP through MSN Messenger, don't send or receive files through it, and turn off file and folder sharing. \n\nFor an added layer of security kit yourself out with a decent firewall. You can download ZoneAlarm for free from www.zonelabs.com

You can find out information about the owner of the IP address, the IP address location (and location of the owner), contact info for the owner of the address, approximate geographical location of the IP address, domain name for the IP address if applicable, classification of the IP address, and a few other useful things.\n\nhttp://bloodrane.gdshadow.net/etc/misc/ip?127.0.0.1\nhttp://whois.domaintools.com/127.0.0.1\n\nIf you want to use the IP address for anything illegal, I can't help you. Rather won't, but if "can't" is what it takes for people not to ask, that's it.

If the hacker has put a trojan / backdoor server on your machine, it will just "phone home" and tell him the new address.\n\nYou will need to clean that out first using various security programs like AVG, Ad-Aware and Scotty (all are free). And use them.

Anyone can gain access to you IP address, but as previously stated, you should be safe.  It take a lot of hard work and long hours to get the exact location of a person based on their IP address.  It can be done, but it is long and tedious to accomplish.  kinda like one of those puzzles where you trace the line from one thing to see where it will end up on the other side, except the line is very thin, there are millions of other lines, and the line if VERY long.  Tedious process to get to the origin.  I would not worry about it really.  You can get security programs that will help prevent people from accessing your computer through your IP address and various ports if you feel unsafe because of it.

There are databases that can be checked against to see where the IP address originates from.\n\nThey simply perform a check using the visiting IP address against these databases to get the location.

your computer has its very own ip address, through the ip address, people can find out, where you are from you internet connection, there is also some personal information, but dont worry, only the government is cappable of doing this, but beware of hackers!

your ip address is able to be found , and so is mine, and everyone elses, but unless you are on a static ip, i would not worry so much. as for finding your real identity,  not by ip address(providing your are on a dynamic ip). just be careful as to exactly how much personal info(name, birthdate, where you live, etc) that you actually put out on the net.

This is a very difficult task, though not impossible.\nYou have to have sufficient cause/reason and then you can approach the IP provider(most probably the ISP of the person) to release the personal information about the user of the IP.\n\njainnys\nMind Experts Inc.\nhttp://www.mindexp.com
