Expiry date
As they state on their site, Intec NetCore get the data for their countdown timer from the analysis at http://www.potaroo.net/tools/ipv4/index.html
Another use of this data is at http://atchoo.org/ipv4/ , where I started logging the date predictions. It shows that the predicted date is extending into the future, for better or worse.
