just another .mmdb

This is another .mmdb which initially is build to verify existing geo data with real measurements.
However it works like any other .mmdb you can find on the Internet.

The goal is to update this .mmdb weekly.
You can get the .mmdb here: https://yammdb.serv.app/geo.mmdb
Raw data can be found here: https://raw.serv.app/

Limitations

• This is not convering the entire IPv4 space, roughtly from 975k routed subnets, we have data on about 717k.
• 1.1.1.1 like any other anycast IP will return incorrect data, the IP has to be unicast

Locations
Currently we have Servers in the following locations, we use to take measurements.

This list will likely be expanded, if you want to sponsor us a virtual server for this, you can hit me up.

Structure
The Datastructure is the following.

Install dependencies for python example

pip3 install geoip2

Example
Reading the data is as easy as:

import geoip2.database

reader = geoip2.database.Reader("geo.mmdb")
response = reader.city("1.1.1.1")
print("Continent",response.continent.code)
print("Country",response.country.iso_code)
print("Latitude",response.location.latitude,"Longitude",response.location.longitude)
print(f"Latency {response.location.accuracy_radius}ms")

Currently accuracy_radius is used for the latency measured, since custom fields are not possible in the default reader.
