NAME

Sort::Key::IPv4 - sort IP v4 addresses

SYNOPSIS

use Sort::Key::IPv4 qw(ipv4sort);

my @data = qw(1.1.1.1 1.1.1.0 1.1.1.2 2.1.0.3);
my @sorted = ipv4sort @data;


use Sort::Key::IPv4 qw(ipv4keysort);

my @sorted = ipv4keysort { $_->ip_address } @hosts;

DESCRIPTION

This module extends the Sort::Key family of modules to support sorting of IP v4 addresses.

IPv4 addresses have to match the regular expression /^(\d)+\.(\d)+\.(\d)+\.(\d)+$/.

FUNCTIONS

The functions that can be imported from this module are:

ipv4sort @data

returns the IPv4 addresses in @data sorted.

ripv4sort @data

returns the IPv4 addresses in @data sorted in descending order.

ipv4keysort { CALC_KEY($_) } @data

returns the elements on @array sorted by the IPv4 addresses resulting from applying them CALC_KEY.

ripv4keysort { CALC_KEY($_) } @data

is similar to ipv4keysort but sorts the elements in descending order.

ipv4sort_inplace @data

ripv4sort_inplace @data

ipv4keysort_inplace { CALC_KEY($_) } @data

ripv4keysort_inplace { CALC_KEY($_) } @data

these functions are similar respectively to ipv4sort, ripv4sort, ipv4sortkey and ripv4sortkey, but they sort the array @data in place.

ipv4_to_uv $key

converts the IPv4 value to a 32 bits unsigned integer.
