The IP's were just to the right of the contributor's name, where the "Report This Comment" would normally be. I'm not sure if the [X] was present or not. It displayed the 1st 3 IPv4 octets but the last octet displayed as dashes: 123.456.789.--- <<<this of course is not a real address.
Next to your name however, was the word "Moderator". No IP. I was viewing the site using Google Chrome.
At 1st I thought you guys might have made some changes, for god knows what reason. Then I checked other posts to see if they also had displayed IP's, but that was not the case. I had refreshed quite a few times and the IPs were still there. But after I made my 1st comment I refreshed again, and it displayed as it usually does.
If the last octet would have displayed that would have REALLY freaked me out. I'm kind of big on privacy. So, even people knowing my general location and provider is a little troubling, but not devastating.
I will continue to try to replicate this and get a screen capture,
