There is also another option using geoip tools using the maxmind.com
database.
http://www.maxmind.com/app/geoip_country
Completely free. one download a month, so no thousands of DNS queries
and you no longer have to maintain a list of country IPs.

I am using the perl API and have been for at least 4 years with no
issues as all :)
