Here you can find regularly updated GeoIP legacy databases.

Data is in plain ascii encoding (converted from UTF-8 with Python unidecode module, umlauts normalized).
No guarantees, but build process verifies the resulting files very carefully.

GeoIP-legacy.csv can be used to update iptables xt_geoip module.
It is built using https://github.com/mschmitt/GeoLite2xtables.

It's enough to check/download once a week, use the example geoip_update.sh script if needed.
 Always audit any downloaded scripts before running (especially as root). :-)
