Range of ip addresses where can I download the database?

Question

Geolocation

Guys, on our site the city is determined by ip, ip is included in the range. And accordingly displays the corresponding city.
We have it in this form.

The base is very large, it is a small piece.
So, the database is outdated, some cities are not detected from mobile phones, do not tell me where you can download a fresh one.
It’s just that the problem is what the previous developer did and didn’t say what kind of database and where it was downloaded from, all of a sudden someone came across, please tell me at least the name, I’ll find it.
And then we have a zapar because of this.
I will be grateful to everyone.
