OT, kinda.... Finding IP addresses

[Fuzzmuncher]

How do I go about finding who an IP address belongs to? One particular trouble maker keeps popping up and I wanted to know how to trace him. Thank you.

whois -h whois.arin.net IP

 

[Fuzzmuncher]

Pardon the ignorance, but where exactly do I enter this?

Here, just go to arin's IP lookup site. The command goldboyd gave you was for use in *nix computers.
