Net::IP::Match::Bin version 0.10
=============================

NAME
    Net::IP::Match::Bin - Perl extension for match IP addresses against Net
    ranges

SYNOPSIS
      use Net::IP::Match::Bin;

      my $ipm = Net::IP::Match::Bin->new();
      $ipm->add("10.1.1.0/25", ...);
      ...
      $ipm->add("192.168.2.128/26", ...);

      $cidr = $ipm->match_ip("192.168.2.131");

DESCRIPTION
    This module is XS implementation of matching IP addresses against Net
    ranges. Using similar method to Net::IP::Match::Regexp in storing Net
    ranges into memory. By implementing in XS C-code, and does not use
    regexp, more fast setup time and less using memory. This module is
    useful when Net ranges change often or reusing range data won't be
    suitable.

METHODS
    new()
        Create IP range object and initialize it.

    $ipm->add( $net | $arrayref | $hashref, ... )
        Add Network address (xxx.xxx.xxx.xxx/mask) into the object. mask is
        1 .. 32 CIDR mask bit value.

            $ipm->add( [ "10.1.0.0/16", "10.2.2.128/25", "192.168.0.0/27" ] );

            $ipm->add( { "10.1.0.0/17" => "Net A", "10.2.2.0/24" => "Net B",
                        "192.168.0.0/27" => "Net X" } );

        When HASH ref is used as arguments, match_ip() returns the value
        when matched. Note that CIDRs could be aggregated internaly, these
        values may be lost in aggregation.

    $ipm->add_range( $range_str, ... )
        Adds IP range into the object. $range_str would be

            $range_str = "1.2.3.4-10.20.30.41";

    $cidr = $ipm->match_ip( $ip )
        Searches matching $ip against previously setup networks. Returns
        matched Network in CIDR format (xxx.xxx.xxx.xxx/mask). or undef
        unless matched.

    $list = $ipm->list()
    @list = $ipm->list()
        Lists the current CIDR list which has been added previously. CIDRs
        are aggregated internaly and the list shows this internal data. In
        scalar context, list() returns reference to the array. On list
        context, returns array itself.

    $ipm->clean()
        Remove redundant CIDR data from the object. Note that this method
        does not free memories, so, if you would like to, generate list()
        and create new object from it.

FUNCTIONS
    match_ip($ip, $cidr1, $cidr2,...)
        function call match_ip() acts like as Net::IP::Match 's same name
        function. searches IP of first argument matches againsts others.
