IP logging question with the newest version of VBulletin
 

I have had a VBulletin board back in the day. It has been awhile, and I'm thinking about getting the newest version. I'm up to date on most of the new features and whatnot but couldn't find specific questions about IP logging.

I already know when a new member registers, his IP will be logged. What I want to know is, will his IP be logged EVERYTIME he logs into the forum, or only if he posts? For instance, if he never posts, but logs into the same account under numerous different IP addresses, will VB log that, or will I only catch it if he posts?

Thanks.
