Use Symfony\Component\HttpFoundation\IpUtils

Problem/Motivation

Currently the wildcard system doesn't work well for subnets.

Steps to reproduce

The problem with the wildcard system is it does not reflect how a subnet behaves. So in the case of having a network of 10.100.5.16/28 it's impossible to white this range. The closest you get is 10.100.5.* but this incorrectly whitelists 10.100.5.255 and 10.100.5.0 which reside on a different subnet.

Proposed resolution

Use Symfony\Component\HttpFoundation\IpUtils::checkIp(). This fully supports all the necessary IPv4 and IPv6 netmask representations.
