Migrating to MaxMind GeoIP2 for Python3

With Python2 now EOL, one of my tasks was to replace old python2/geolite2 code with python3/geoip. This does require a subscription to MaxMind to either make the calls via web or download static database files, which fortunately was a option.

Installing Python3 GeoIP2 package

On Ubuntu 20:

  • apt install python3-pip
  • pip3 install geoip2

On FreeBSD 11.4:

  • pkg install python3
  • pkg install py37-pip
  • pip install geoip2

Verify successful install

% python3
Python 3.7.8 (default, Aug  8 2020, 01:18:05)

Sample Python Script

#!/usr/bin/env python3

import sys
import geoip2.database

ipv4_address = input("Enter an IPv4 address: ")

with geoip2.database.Reader('/var/db/GeoIP2-City.mmdb') as reader:
        response = reader.city(ipv4_address)
        sys.exit("No info for address: " + ipv4_address)
    if response:
        lat = response.location.latitude
        lng = response.location.longitude
        city = response.city.name
        print("lat: {}, lng: {}, city: {}".format(lat, lng, city))
