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.
