At a ceremony held on 3 February, 2011 the Internet Assigned Numbers Authority (IANA) allocated the remaining last five /8s of IPv4 address space to the Regional Internet Registries (RIRs) in accordance with the Global Policy for the Allocation of the Remaining IPv4 Address Space. With this action, the free pool of available IPv4 addresses is now fully depleted.
“This is truly a major turning point in the on-going development of the Internet,” said Rod Beckstrom, ICANN’s President and Chief Executive Officer. “Nobody was caught off guard by this, the Internet technical community has been planning for IPv4 depletion for quite some time. But it means the adoption of IPv6 is now of paramount importance, since it will allow the Internet to continue its amazing growth and foster the global innovation we’ve all come to expect.”
I’m debating whether I want to add an IPv6 address for this humble site now, or wait until it becomes mandatory. (It won’t replace the existing IPv4 address, at least at first.)
