We've been dealing with geoip issues for quite a while and this is what we
came up with, maybe it would be useful for you
https://github.com/jsdelivr/globalping/blob/master/docs/geoip.md

But we're also in progress of updating the logic to include latency as an
additional parameter.

What are you guys using as a reliable GeoIP database ? I've tried Maxmind
and a few others, also checking against ARIN but there's tons of
differences.

For example: 1.2.9.0/24 . ARIN says it belongs to China Telecom but
others say it's part of Russia: https://ipregistry.co/1.2.9.0

How to handle such cases ?

Thanks!
