<br>
Yes, the projection on <a href="http://ipv4.potaroo.net" target="_blank">http://ipv4.potaroo.net</a> does account for the<br>
new global policy. I added this last year, so that IANA exhaustion<br>
effectively occurs at the point when there are 5 remaining /8s in the<br>
IANA unallocated pool.<br>
<br>
The consumption of IPv4 addresses continues to decline in relative<br>
terms, and the projected exhaustion dates continue to push out by a<br>
few months (<a href="http://www.potaroo.net/tools/ipv4/predict.png" target="_blank">http://www.potaroo.net/tools/ipv4/predict.png</a> shows the<br>
predicted exhaustion date over time). The current consumption rate of<br>
around 12 /8s per year looks rather stable at the moment (<a href="http://www.potaroo.net/tools/ipv4-alloc/fig25.png" target="_blank">http://www.potaroo.net/tools/ipv4-alloc/fig25.png</a><br>
) so the 27 remaining IANA /8s look like taking a little over 2 years<br>
to be used.<br>
