Usage

use Hyqo\Utils\Ip\Ip;

Ip::isValid('192.168.1.0'); //true
Ip::isValid('0:0:0:0:0:0:0:1'); //true

Ip::isMatch('131.0.72.199', '131.0.72.0/22'); //true
Ip::isMatch('131.0.76.199', '131.0.72.0/22'); //false

Ip::isMatch('132.0.72.199', ['131.0.72.0/22', '192.168.1.0/31']); //true

Ip::normalize('127.0.0.1:80'); //127.0.0.1
Ip::normalize('[::1]:80'); //::1

Ip::port('127.0.0.1:80'); //80
Ip::port('[::1]:80'); //80

The Ip class automatically detects IP version, but you can use Ipv4 and Ipv6 classes with the same methods as well.
