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.
