geoip - Where does MaxMind get its data and how can you access it? -


from sources geolocation databases http://www.maxmind.com/ data? have understood ip registry places arin , ripe hold information company assigned ip range has isp's right? if so, there has way of accessing this.

there number of maxmind databases, free , commercially licensed. in part, information in these databases comes other public databases, such ripe , in part maxmind's internal processing/matching.

you can write own tools parse ripe database, extract of fields , build own database if want, or can pay has done it.

if going query databases programatically, there apis on dev.maxmind.com languages.

just word of caution - if use maxmind geoasn database lookup asn ip, name not match isp name associated given ip. (e.g. as2856 resolves many different organisations, incl. bt , talktalk). why geoisp database keyed off ip address ranges, rather asns.
