NAME
    Net::IP::LPM - Perl implementation of Longest Prefix Match algorithm

SYNOPSIS
      use Net::IP::LPM;

      my $lpm = Net::IP::LPM->new();

      # add prefixes
      $lpm->add('0.0.0.0/0', 'default');
      $lpm->add('::/0', 'defaultv6');
      $lpm->add('147.229.0.0/16', 'net1');
      $lpm->add('147.229.3.0/24', 'net2');
      $lpm->add('147.229.3.10/32', 'host3');
      $lpm->add('147.229.3.11', 'host4');
      $lpm->add('2001:67c:1220::/32', 'net16');
      $lpm->add('2001:67c:1220:f565::/64', 'net26');
      $lpm->add('2001:67c:1220:f565::1235/128', 'host36');
      $lpm->add('2001:67c:1220:f565::1236', 'host46');


      printf $lpm->lookup('147.229.100.100'); # returns net1
      printf $lpm->lookup('147.229.3.10');    # returns host3
      printf $lpm->lookup('2001:67c:1220::1');# returns net16

DESCRIPTION
