We use a cronjob to curl and untar every month across our multiple application servers (so each copy is independent per machine, saves the query on the database.) http://www.maxmind.com/download/geoip/database/GeoIP.dat.gz Pluging it in was easy: def ip_country(ip) g = GeoIP.new('/var/lib/geodata/GeoIP.dat').country(ip) return g[3] end we use something very similar but it’s called GeoIP.

I've twice seen projects where not only did they pay for the long/lat-to-city/state data, but they queried it via a web service. Not "super fast" at all. Thanks for documenting.
