IPV4 geolocation is based on maintained databases (e.g. Ma Mind) that usually are city or street accurate.
The popular rhetoric that having an IP is having the location is most often wrong unless Your users have static IPs registered to them. The way law enforcement does it is by subpoening the owner of the IP of pointing to the user associated with the IP at specific time but that still is prone to errors because of NATs - many distinct clients behind a single address.
All in all fingerprinting is using IPs pretty rarely nowadays.

- kortilla 6y agoCGNAT means sometimes an IP just identifies an entire ISP and nothing more.
- ecabuk 6y agoI bet Google can do better job than the MaxMind but even the city accuracy isn’t that enough? I think it is enough to effect your localized ads.
