Match IPv4 address given IP range/mask?

Question

Either with PHP or a RegExp (or both), how do I match a range of IP addresses?

Sample Incoming IPs

10.210.12.12
10.253.12.12
10.210.12.254
10.210.1

Use this library: https://github.com/S1lentium/IPTools

//Check if IP is within Range:

echo Range::parse('192.168.1.1-192.168.1.254')->contains(new IP('192.168.1.5')); // true
echo Range::parse('::1-::ffff')->contains(new IP('::1234')); // true
