If you wanted to trace an IP address because that IP Address was the source of attacks and abuse, how would you accomplish this? Is there anything one can do to find who is using a given IP address and furthermore is there anything that can be done to stop it?
Update: The destination (where the server is) is in the USA. The source indicates that it is also USA but like someone suggested, the IP Address is likely spoofed... I'm still open to further input/details...
