Hi, I was messing with rethink dns to see what was its possibilities. then I saw this “surprise”. Is this a normal behaviour ? Do we know what it does ? Does anyone has observed this on its phone ?
Edit : got an answer on eOS forum, it confirms what you guys told me :
rethink uses ipinfo lite (db-ip.com before) - their info atm says germany. it’s a hetzner ip anyway. If you trace the network path you’ll see it’s their fsn1 datacenter.
incorrect display of GeoIP data · Issue #2499 · celzero/rethink-app · GitHub
It looks like there could be a bug in how Rethink “searches” IP ranges to geo location… Rethink doesn’t use the mmdb format, but pre-processes the csv (code) to make it “searchable”.
Thank you all for your help :)


Mostly why this server. As ntfy sounds like notify, I believed it is for pushed notification, which has been confirmed by someone.
Yes, this is for push notifications to work. When running a degoogled OS I’d expect to not ping google about my notifications. I haven’t heard of a proof that google used it to track us but I wouldn’t be surprised. Also, from time to time apps without gapps have problems with google’s push for unknown reasons. In order to work any push service needs an external server to ping
As for the IP, this shows something else. But as others mentioned those lookups are mostly guesswork and country ranges
