That's probably because it's best-guessing the IP address - usually it says (guess) right next to the results

if the guess give different cities every time it must be an random guess, not a calculated guess else it will give always the same city because geodatas are not updated every seconds.

Guessing works finding the next-best subclass.

If it's a calculated guess, why it's random and never same ?
Else it's maybe good to provide all solutions if several exists.

Well, I say random because it takes a random "guess" each time around instead of listing the results. Simpler on the API

Today,
how many IP are guessing ? (in %)

All professional geoIp City providers say that they have 85% of true data (with satellite and proxy).

This database has no regular update,
don't have satellite and proxy datas,
some wrong algos to retrieve datas based on some old systems,
a lot of holes guessed,
ect ...

Can we say than only 30% - 40% of city data are true ?
