1 Check out http://www.samspade.org/ . The whois function will tell you who owns the netblock. Lots of dialup/cable/dsl connections don't necessarily have any publically available use data about them, as they're dynamically assigned. Whois tells you at least who owns the IP address. What is it that you're trying to do? drop me a line, if you like.

2 If you just want to know what town it's coming from, go here and type the address in the first box. That will give you city and state. To find the controller of the ip, open up a dox box (start->run->type in 'cmd' ). When the window opens, type 'nslookup ' except replace with the real ip address. That'll give you the hostname with the true owner of the domain. do a whois on that to find out who to contact. If you do a whois on the ip address, you will get misleading information because of different subnet ownership.
