"Today marks the official launch of IPv6, the new Internet Protocol that's permanently being deployed by ISPs in more than 100 countries, home router equipment manufacturers and leading websites like Google, Facebook, YouTube and Yahoo.
Parties committed to the new protocol will now make IPv6 the "new normal" from here on out, expanding the Internet from its current four billion IP addresses to over 340 trillion, trillion, trillion addresses. That said, the End of the Internet is no longer in view.

"The support of IPv6 from these thousands of organizations delivers a critical message to the world: IPv6 is not just a 'nice to have'; it is ready for business today and will very soon be a 'must have,'" said Leslie Daigle, Chief Internet Technology Officer, Internet Society. "We believe that the commitment of these companies to deploy IPv6 will ensure that they remain industry leaders. Any company wishing to be effective in the new Internet should do the same."

Starting June 6 at 0000 UTC, major websites are permanently enabling IPv6 on their main sites. ISPs will permanently enable IPv6 across a significant portion of their current and all new residential wireline subscribers. Home networking equipment manufacturers will enable IPv6 by default through their range of home router products."
