Net::IPv4Addr 0.10

Net::IPv4Addr is a Perl extension for manipulating IPv4 addresses.

SYNOPSIS
use Net::IPv4Addr qw( :all );

my ($ip,$cidr) = ipv4_parse( "127.0.0.1/24" );
my ($ip,$cidr) = ipv4_parse( "192.168.100.10 / 255.255.255.0" );

my ($net,$msk) = ipv4_network( "192.168.100.30" );

my $broadcast = ipv4_broadcast( "192.168.100.30/26" );

if ( ipv4_in_network( "192.168.100.0", $her_ip ) ) {
print "Welcome !";
}

etc.

Net::IPv4Addr provides functions for parsing IPv4 addresses both in traditional address/netmask format and in the new CIDR format. There are also methods for calculating the network and broadcast address and also to see check if a given address is in a specific network.
