As part of World IPv6 Launch on June 6, 2012, Google and other web companies such as Facebook, Bing, Comcast, and Cisco will come together to permanently enable IPv6. Google will support access via IPv6 as well as IPv4 from now on. This launch follows World IPv6 Day – IPv6’s successful global-scale test run on June 8, 2011.
What is IPv6?
The Internet Protocol (IP) is the language that computers use to communicate with each other on the Internet; it works much like phone numbers, which let us connect one telephone to another.
Internet Protocol version 6 (IPv6) is the new version of the Internet Protocol. The addresses used by the current version of the Internet Protocol, IPv4, are nearly all used. It is believed that IPv6 is essential to the continued health and openness of the Internet – and that by allowing all devices to talk to each other directly, the launch of IPv6 will enable future innovation and growth for the Internet.
IPv6 connectivity issues
Over 99.9% of users do not have any problems going to IPv6-enabled websites. However, in rare cases, users may have IPv6 enabled, but not working properly. This may cause delays and connection problems when visiting Google and other participating websites.
IPv6 connectivity problems are usually caused by misconfigured or misbehaving home network equipment (e.g., home routers), bugs in operating systems, or issues with your Internet Service Provider (ISP).
If you experience delays connecting to IPv6-enabled websites, you can work around the problem using one of the following:
- Upgrade to the latest version of your browser. Older versions of many browsers have known bugs with IPv6, and later versions may incorporate workarounds for IPv6 connectivity-related issues in operating systems, routers, and ISP’s.
- Install a browser that includes workarounds for IPv6 connectivity problems, such as Google Chrome.
- Contact your Internet Service Provider (ISP), such as Comcast, AT&T, or Time Warner, about IPv6.
If you are still experiencing connectivity issues, here are some additional suggestions for common operating systems:
(Windows 7 / Windows Vista Windows XP)
