We use the free MaxMind ip to location binary database

Their wesbite offers this under GeoLite if anybody is interested.

An active implemetation of the ranges would still require conversion to Rewrites and comparison of ranges to other countries (possibly creating extra work and ranges more focused than necessary) ranges to verify missing ranges.

Although it may seem that I'm attempting to discourage folks from this implementation, my intention is rather, in providing as much caution and detail as possible. (I've had strict limitations for non-North American visiors in place for more than seven years).

there's also a website (also I have NOT checked the accuracies):

block a country

These Ranges require conversion to Rewrites as well.
