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.

Hi relay operators,
as you might have heard, MaxMind has changed access and use of their GeoLite2 databases:

This affects Onionoo and tor, and I'm trying to find a working alternative on the following ticket:
https://trac.torproject.org/projects/tor/ticket/32978
Today I think I found a possible alternative by using data from another provider. But before I name it here, I'd first want to find out how accurate it is.
I tried resolving relay IP addresses of relays that have been running in the past week and compared that to our existing lookups using MaxMind's October database.
The result is that 7669 relays (93%) had the same country code and ASN.
I put the remaining 7% on the following wiki page:
https://trac.torproject.org/projects/tor/wiki/doc/MetricsGeoipComparison
I'd like to hear from you which data source is right and which is wrong (or if both are wrong).
If you'd like to help, please leave comments on the ticket or in the "Comment" column on that wiki page by February 19, 2020.
Thanks for helping!
All the best, Karsten
