Google Public DNS Serves 70 Billion Requests Per Day [googleblog.blogspot.com]
We launched Google Public DNS in December 2009 to help make the web faster for everyone. Today, we’re no longer an experimental service. We’re the largest public DNS service in the world, handling an average of more than 70 billion requests a day.
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, 220.127.116.11 and 18.104.22.168.
