Folk, The Ruby GEM for GeoIP has been updated (now v0.2.0) to support the GeoIPCity database. In the process, an incorrect translation from the C language original has been repaired, so the new Gem correctly identifies the database version. Note: this is a pure Ruby GeoIP, unrelated to Sean Chittendon's wrapper around the official C api. Usage: require 'rubygems' require_gem 'geoip' p GeoIP.new('GeoIPCity.dat').city('lazaridis.com') -> ["lazaridis.com", "212.227.109.28", "DE", "DEU", "Germany", "EU", "01", "Karlsruhe", "", 49.0047, 8.38579999999999] Please don't use this latitude/longitude for targeting, as he is/was recently actually in Northern Greece :-).
