how to know the owner of an IP ?

[haneo]

I just know the existence of RIP.net database, but i can't find all the IPs and their owner, i have heard that RIP contains the European databases.

Is there any other Web databases that i can answer because i have found in our Web Server Logs, suspisious data!

thanks.

Another good one is

http://www.securityspace.com

At the bottom of their page, they have a 'whois' link which will perform an international whois lookup.
