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 ?
The trouble with all the IP Geo providers is they're selling data based on: 1) Assumptions 2) Unmaintained data 3) Stale data RIR records are notorious for being unmaintained (by the member...I'm not blaming ARIN/RIPE/etc.). Same goes for rDNS...again, because the owner of the space doesn't care enough to keep it up to date...because it's not generally of operational importance to them. Some networks will publish geofeeds, but getting all the IP Geo providers to consume those is like herding invisible cats. And don't get me started on end-users who consume data from an IP Geo provider and "set and forget" it...ending up with years old data, based on which they deny network or website access. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route Blue Stream Fiber, Sr. Neteng | therefore you are _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
