Interesting but this isn't actually how geolocation is done, right? The ARIN/RIPE data isn't sufficiently accurate to be useful beyond country. Commercial geolocation involves correlating client IP vs known physical location e.g. from WiFi AP or mailing a package to the user. At least that's what I have been told over the decades.
- shortrounddev2 3y agoI work in adtech and this is how we do geolocation. There's also device geolocation but if the user doesn't consent to sharing their GPS data with us, we just use IP address for targeting. Common provider for this is Maxmind; they ship a database that you host locally and query
- dawnerd 3y agoEven the free maxmind db is accurate enough for most applications.
- tiffanyh 3y agoDoes Cloudflare have the same data as Maxmind? Because Cloudflare and Maxmind geolocate me to the exact same longitude/latitude.
- klaussilveira 3y agoCloudFlare uses Maxmind: https://developers.cloudflare.com/support/network/configuring-ip-geolocation/#troubleshooting https://developers.cloudflare.com/support/network/configurin...
- klaussilveira 3y agoSince you are in adtech: do you buy MaxMind, or roll your own? Are there any providers for US-only data, and therefore, cheaper?
- shortrounddev2 3y agoWe licensed Maxmind's DB recently (it's like $300 a year or something). idk if there are US-only databases. Our customers are all in the US, and we use geo IP to filter european users for compliance (GDPR and otherwise)
