This is factual. I spend a significant amount of effort ensuring geoip is accurate for our customers and the proliferation of vendors makes this very annoying and time consuming when we are onboarding a new block. RFC9632 at least makes this easier - I definitely recommend doing so if you are not.

I don't feel like there is any reliable GeoIP database. The protocol wasn't designed for this and thus there is a lot of false information presented about where IP addresses are located.

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!
