In a post out yesterday, “Google Public DNS: 70 billion requests a day and counting“, Google reminded us all that their Public DNS service supports IPv6 at these addresses:
From Google’s post:
We’ve also taken steps to help support IPv6. On World IPv6 Day, we announced our IPv6 addresses: 2001:4860:4860::8888 and 2001:4860:4860::8844 to supplement our original addresses, 126.96.36.199 and 188.8.131.52.
If you are working in an IPv6 environment, you can configure your system to point to these addresses for DNS services. (Typically in the settings or control panel for your operating system.) This can greatly help as you migrate your network to IPv6 or establish a trial network.
With World IPv6 Launch coming up on June 6, 2012, it’s great to have resources like these from Google that allow people to work in an IPv6 world!
