Why is it necessary to test for ip?

[jamsea]

IP address is a special case for wildcat. Before we introduced code to do domain aliases we weren't able to resolve them, so the logic in the rest of the function is assuming that the host isn't an IP address. Without this IP address check lines 16-18 bail out and cause tests to fail when you have a valid IP/domainAlias match
