If you are looking for something automagic - I dunno.

Bit in special cases I always try a traceroute (or tracert for the M$ 
people). It usually indicates quite clear where the IP is located. The 
routers on the route usually have some sort of geographic code included.

Not exactly bullet-proof but always worth a try IMHO.

Unfortunately more and more routers will block traceroute attempts due 
to some abuse and possible security issues that some admins might think of.
