Thanks Paul! Perfectly clear now!
I was going to change the
Session IP Octet Length Check to use the full IP address, but the notes that go with it gave me pause. Seems that using the full IP for session IDs can cause trouble for users behind transparent proxies (and there are many of those). So, I'll leave things as they are now, and live with it. Of course, you have my vote to use your own guest ID solution for the mod. It would make a great add-on even better!
