The DBIP geolocation database is generated from sparse data without
compaction.  Two different ISP's in the same country might have
adjacent CIDR blocks, and when aggregated as "country" data, may
be merged to conserve space.  This package facilitates this.

There are scripts to download and preprocess the GeoIP database
for iptables-mod-geoip which require this Perl module.
