I have some partial IP addresses from the IRC server our channel resides on. To protect the users, IP addresses and hostnames are partially masked.
One IRC user in particular spiked our attention when they started garnering an unhealthy interest in a rather vulnerable member - I won't bore you with the details.
In a nutshell, I need to search my XenForo User Database for an IP in the form: "*.*.X.Y". (e.g. "*.*.111.255") This is a challenge, because it's completely the other way around from what would be expected.
Thanks for the assistance. It's a rather serious matter that I need to get sorted out if at all possible, and it could potentially lead to a restraining order on someone if I find the information I expect to find...
