Question : Does an internet map exist that shows the physical location of IP address?

I was wondering if a table of ip addresses and their physical (general of course) exists.

For example, If someone from 216.243.32.345 attempts to access my website, I can grab that IP address, however how can I check to see what country this is most likely from?

I understand I can do a reverse look up, however this isn't an exact solution.

Thanks.
