tracking ips to country
 

Im looking for an tool to either install on a web server or as a third party service that can track our end user ip's and show us what country that ip is comming from. Something more granular than just a reverse dns lookup to see what the country extention is. Any help or experiences here would be greatly appreciated.

have looked through that, and we have a pretty good web analysis tool right now, but we need something that has a db of global ips to country so when we buy traffic we know exactly what country it is comming from.
