MaxMind would do the job for you. Mind you, that there is a huge difference between the paid for version and the free version. The free data is collected from open sources like RIPE/ARINN etc. vs. the paid for database is the data, that they receive from ISPs. ISPs like Digiweb, Perlico, UPC and for example the 3g carriers don't care about GeoIP whatsoever. Hell, Hutchinson 3g hasn't even asked they upstream to update the RIPE records for their segments.
