geoip-database-contrib binary package in Ubuntu Bionic amd64

 GeoIP is a C library that enables the user to find the country that any IP
 address or hostname originates from. It uses a file-based database.
 .
 This package contains a script that downloads the latest version of the binary
 flavor of the four MaxMind GeoLite databases (Country, IPv6 Country, City, and
 ASN).
 .
 These databases simply contain IP blocks as keys, and countries/cities/ASNs as
 values, which should be more complete and accurate than using reverse DNS
 lookups.
 .
 The MaxMind database itself is made available under a DFSG-compatible license.
 However, it is distributed directly in binary format and the source code for
 generating it is not provided.
