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

[Tim Niemeyer]

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.

Tim
