IP locator services?

[agilent]

Is there a service that could provide information on IP's?
I have some trolls on my site and I would like to gather information about there location. Maybe there is a website where I can type in the IP address and it can give me information about the IP?

Any suggestions are welcome.

Google is your friend. Keep in mind many are really are not that accurate though. Especially if they are using a proxy.
