Why is the lat/lon for my IP in Kansas?

We may blank more granular location values (such as the city or the city and the subdivision) if the users of an IP are spread out over a wide enough area. In this case the lat/lon is usually the center of the most granular resolution we return.
So, if we believe the users of your IP are mostly in the US, but aren’t certain about the city and state, we may leave them blank. In this case the lat/lon will correspond to the center of the US which happens to be in Kansas.
