Sometimes it just because they have to announce to another region without changing IRR. They are a lot of geolocation database, but only ipip and ipinfo can correct the geolocation based on BGP routing information. I'm assuming ipinfo is doing some scan, if the subnet have too many open 22 or 443

100%. We have certain things we do here at ThreatSTOP that isolate some locations based on the upstream provider because all of the GeoIP databases are wrong. If we collectively understand that GeoIP is “best guess” or “best attempt” and not gospel, we’d all be better off. — Joel Esler Vice

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. On Mon, Feb 3, 2025 at 10:28 AM Dmitriy A. wrote: > We've been dealing with geoip issues for quite a while an

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. On Mon, Feb 3,

IPInfo would be a solid choice, but MaxMind is also reliable in most cases. However, some IP databases often provide inaccurate results, and I would recommend avoiding IPStack. ARIN WHOIS is updated by the IP owner or user and can often be outdated or inaccurate, as many operators do not update it
