http://games.juhlin.com/maps/resources/iptest.html ( I have a good sampling so no further testing is needed)
This should redirect you to a Google map based on your location.
I expect one of four results.
Map near your location.
Map within your country but not near your location.
Map outside your country.
Map at point 0,0 just off the coast of Nigeria.
Unfortunately my internal network IP is not usable for testing.
Can you guys let me know which one you guys see.
