Frequently asked questions:
1. Why ipextra.com?
We created ipextra.com as a fun mash-up project to play around with Google Maps (because it's cool) and Yahoo! Local (because it's useful). At the time Google Local didn't have a decent API or we probably would have used it.
2. How we (try to) find your location:
We use a service provided by HostIP.info ( http://www.hostip.info ) We use their service mostly because it's free but it works pretty well too. They have a few different APIs to work with.
