NAME
    Net::IP::Match::Trie - Efficiently match IP addresses against IP ranges
    with Trie (prefix tree)

SYNOPSIS
      use Net::IP::Match::Trie;
      my $matcher = Net::IP::Match::Trie->new;
      $matcher->add(google => [qw(66.249.64.0/19 74.125.0.0/16)]);
      $matcher->add(yahoo  => [qw(69.147.64.0/18 209.191.64.0/18 209.131.32.0/19)]);
      $matcher->add(ask    => [qw(66.235.112.0/20)]);
      $matcher->add(docomo   => [qw(124.146.174.0/24 ...)]);
      $matcher->add(au       => [qw(59.135.38.128/25 ...)]);
      $matcher->add(softbank => [qw(123.108.236.0/24 ...)]);
      $matcher->add(willcom  => [qw(61.198.128.0/24  ...)]);
      say $matcher->match_ip("66.249.64.1"); # => "google"
      say $matcher->match_ip("69.147.64.1"); # => "yahoo"
      say $matcher->match_ip("192.0.2.1");   # => ""

DESCRIPTION
    Net::IP::Match::Trie is XS or Pure Perl implementation of matching IP
    address against Net ranges.

    Net::IP::Match::Trie uses Trie (prefix tree) data structure, so very
    fast lookup time (match_ip) but slow setup (add) time. This module is
    useful for once initialization and a bunch of lookups model such as long
    life server process.

METHODS
    add(LABEL => CIDRS)
          LABEL: Str
          CIDRS: ArrayRef

        register CIDRs to internal data tree labeled as "LABEL".

    match_ip(IP)
          IP: Str

        return "LABEL" if IP matched registered CIDRs. otherwise return "".
