Forum Members registering using my server's IP
 

I reported this issue to my hosting company who told that this is an existing issue with vbulletin. I did a quick search here in the forum but didn't see anything about it.

Basically a couple of new members have recently registered using my server's IP address. I only caught it because I moderate all new members.

Is this a true issue and if so, is there something that can be done?

Thanks!
