You can trace but you are going to get an geographic area. Those traced are thraced with the assistence of the ISP. The ISP handles the allocation of IP addresses and "knows" who has what address. If it is a customer of theirs, they know who that customer is and probably have a mailing address for the person. IF you have the IP address, you can use a utility like visual trace rout to see about where the address is. You will definitely get a country and may get it narrowed down by as much as a state or even city.
