Google will enable IPv6 for its main websites including google.com


Web giants including Facebook and Google are braced for a major test tomorrow of new technology designed to allow the internet to continue growing after current systems reach their capacity.
But the internet is not ready. It’s hoped the 24-hour World IPv6 Day test will help concentrate minds at network operators, as a small percentage of users may be unable to reach their favourite websites.
The huge experiment is being run because the Internet Protocol itself – the fundamental set of rules that allows data to be transmitted the internet – is due to be updated from IPv4 to IPv6.
The change is required because IPv4 offers a limited and rapidly dwindling supply of IP addresses, the identifying numbers which are allocated to each computer or network connected to the internet. There are only 4.3 billion IPv4 addresses, compared to 340 trillion trillion trillion IPv6 addresses.
“It's as if the internet was originally designed with a limited number of telephone numbers, and we're soon going to run out,” Vint Cerf, a member of the team that built the forerunner of the internet, explained in January.
The new system should have more than enough capacity to serve existing demand in booming economies like China, and to foster future internet technologies worldwide..

The problem is that IPv4 and IPv6 communications are not compatible with each other: a home PC connected via IPv4 cannot access an IPv6 wevbsite, for example. So network operators need to make technical preparations to ensure users can access websites and other services via either. Some have not, however.
“In all likelihood, you won’t even notice the test,” Google assured users.
“The vast majority (99.95 per cent) of people will be able to access services without interruption: either they’ll connect over IPv6, or their systems will successfully fall back to IPv4."
But it warned there may be problems for a few tomorrow.
“However, as with any next-generation technology, there may be teething pains. We estimate that .05 per cent of systems may fail to fall back to IPv4, so some people may find Google, Facebook, Yahoo, Bing and other participating websites slow or unresponsive on World IPv6 Day.”
Google will enable IPv6 for its main websites including google.com and youtube.com, so that they are accessible via both IPv6 and IPv4, and has provided a page for users to test whether they are likely to experience problems.
