When will we run out of IPv4 Addresses?

The central IANA pool of IPv4 was depleted in January 31 of 2011. The remaining IPv4 addresses in the world are no in possession of the five Regional Registrars and its members. While no one can predict the final exhaustion date of IPv4 in each region with certainty, we all know it is inevitable. I.m proud to say that my prediction of the IANA pool depletion was very good as this static graph over how my prediction changed over time shows.

With the IANA depletion event behind us, it is now time to focus on when each individual RIR will get depleted. However, do not be fooled by looking solely at your own regions depletion date. The Internet is a global network and as such everybody will be affected when the first IPv6 only host connects to the Internet. If you intend to communicate with those hosts, you better implement IPv6. So the first regions depletion date is really what you need to aim to have IPv6 ready.

The numbers above assumes that the demand for IPv4 don.t shift between regions after one region is depleted. If such shift in demand becomes reality, all the central IPv4 address pools will be depleted by
