Re: [tor-relays] Please help us find a working alternative to using MaxMind's GeoLite2 databases



Hi Karsten

For the RIPE Region (the resources from RIPE) the correct source is the RIPE Database. There is an "country" attribute on the inetnum and inetnum6 objects.

Last time I checked maxmind, it was completely wrong about 185.220.100.0/22. I reported to them, but didn't get any response. And it looks as they didn't update since then.

I will check your list for the 185.220.100.0/22 prefixes and report in the ticket, later.
