Our Activity log is filled with constant "Desktop client IP changed" entries from a couple of my users. It only seems to be an issue for IPv6, so I'm not sure if it's specific to their ISPs, if they're using a wireless and wired connection at the same time and that's somehow triggering this, but it's annoying at very least. I'd like to be able to filter that activity "out" when viewing the log but that' doesn't seem possible.
Consider it a feature request if it's not I guess.
