IPv4, the current ip addressing system that we use, is reaching exhaustion. A bold prediction by Internet evangelists (like Geoff Huston of APNIC) is that all IPv4 addresses will be used up by 2012. My exhaustion counter says we only 629 days. It’s nice to look back at how our IPv4 address usage has increased over the past decade – the greatest 10 years of the Internet age I would say.

It’s interesting to note that Asia and the Pacific (through APNIC) used the most number of blocks (/8s) among all five regions. It is such a strong force in the Internet infrastructure sphere, and as such has a big role on IPv6 deployment and rollover.
