Fast lookup of country codes from IP addresses
Finding the home country of a client using only the IP address can be difficult. Looking up the domain name associated with that address can provide some help, but many IP address are not reverse mapped to any useful domain, and the most common domain .com offers no help when looking for country.
This module comes bundled with a database of countries where various IP addresses have been assigned. Although the country of assignment will probably be the country associated with a large ISP rather than the client herself, this is probably good enough for most log analysis applications, and under test has proved to be as accurate as reverse-DNS and WHOIS lookup.
