When Vint Cerf and his friends at DARPA concocted a system that allowed for 4.3 billion IP addresses, it was never conceived that everyone's computer would be able to access the internet -- before the age when your telephone, fridge and air conditioning unit would too. The IPv4 system officially ran out of addresses last year, but fortunately the moment was prepared for: June 8th 2011 was "World IPv6 Day," where a host of sites including Google, Bing and Facebook quietly tried out the new system for 24 hours to make sure it wouldn't cause the internet to explode. June 6th this year will see the final activation of the new network provision that has a capacity of around 340,282,366,920,938,463,463,374,607,431,768,211,456 unique addresses, which we figure will keep us going until Black Friday, at least.
