Perl module to read MaxMind DB files and look up IP addresses

 MaxMind::DB::Reader provides a low-level interface to the MaxMind DB
 file format as described at https://maxmind.github.io/MaxMind-DB/.
 .
 If you are looking for an interface to MaxMind's GeoIP2 or GeoLite2
 downloadable databases, you should also check out the libgeoip2-perl
 package, which provides a higher level OO interface to those databases.
 .
 The MaxMind-DB-Reader distribution ships with a single pure Perl
 implementation of the Reader API. There is a separate distribution that
 provides an XS implementation, which links against libmaxminddb. It is
 packaged as libmaxmind-db-reader-xs-perl and approximately 100 times
 faster than the pure Perl implementation.
 .
 This module is deprecated and will only receive fixes for major bugs and
 security vulnerabilities. New features and functionality will not be added.
