UBB.threads PHP Forum Software Community Forums UBB.threads Version 7/8 Support CP member search by IP wild card

I have some spam coming in form China / Beijing with IPs starting 221.221.

I want to search the Member Management area for Registration IP using a wild card but it returns no entries, even with IPs that I know exist.

I have tried 221.* and 221* but it doesn't work.

Any tips?
