Unless I'm mistaken you do (or at least as close to it as anygone got)
and that is one of the basis of your service!

The point is it probably would not be as accurate as one could hope
because internet network infrastructure is network-centric and not
necessarily region-based. Of course you could try to fully map INET
like CAIDA does and keep the info updated on "daily basis", pretty
hard work though...

Certainly having to support machine on every large network in every
city is rather troublesome otherwise. Of course this is probably
way overkill for IP->Country data.
