Facebook, Google and Yahoo have teamed up to promote the new IPv6 web protocol in a bid to encourage other websites to adopt the new address scheme.
Internet regulators have warned that the older IPv4 Web protocol will run out of web address in November 2011, and have been encouraging websites to switch to the new system as soon as possible.
The Internet giants, along with content delivery networks Akamai and Limelight Networks, are set to switch their main websites to the new IPv6 system for 24 hours on 8 June 2011 as part of the promotion.
In a blog post, Google said that on 8 June, which has been dubbed as the World IPv6 Day, 99.5 per cent of users will not be affected by the change, but that there is a slight possibility that it could create accessibility problems for some.
“We hope that many other websites will join us in participating in World IPv6 Day. Changing the language spoken by every device on the Internet is a large task, but it’s essential to ensure the future of an open and robust Internet for decades to come,” Lorenzo Colitti, a network engineer at Google said in a statement.
