Seeking to analyze web log files by the country of request origin, I recently proposed a simple plugin wrapping hostip.info API. Of course, the major competitor in the field is maxmind geoip and they provide a free light version of their database. This database can be queried through their java API of a geoip Grails plugin.
Time has come for numbers. How each module perform on the same set of ip address? Even with 3% of uncertainties, maxmind geoip lite shows to be clearly the best.
