GeoIPgen is a country-to-IPs generator. It’s a geographic IP generator for IPv4 networks that uses the MaxMind GeoLite Country database. Geoipgen is the first published use of a geographic ip database in reverse to translate from country-to-IPs instead of the usual use of IP-to-country. Features: Random or sorted order, unique or repeating IPs, skips broadcast addresses, one, many or all countries.
