IPv6 will finally go Official live on 6,June 2012

We knew it had to happen eventually, but now we already have an exact date to look forward to. Google has just announced that it will be joining a bunch of other major internet companies in a coordinated launch of the next-generation Internet protocol on June 6 this year.

So as of the start of June, more than 15 years after the official IPv6 specification was published, the world will finally migrate to it. It should be a pretty seamless experience and regular users should not be able to tell the difference.

IPv6 is the replacement for the current version of the Internet Protocol, IPv4, which ran out of addresses quite some time ago.
