ipgeo

libipgeo library is written on top of the IP2LOCATION database allowing the user to do geo-targeting of IP addresses. For a given IPv4 address, libipgeo can lookup the following:

Country Code
Country
Region
City
Latitude
Longitude
ISP

NEW:libipgeo now searchs the IP2LOCATION database in O(lg n) and is TONS faster!

Included with the libipgeo distribution is a simple traceroute client that does IPv4 targeting:
