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.
DNS
acts
like the phone book of the Internet. If you had to look up hundreds or
thousands of phone numbers every day, you’d want a directory that was
fast, secure and correct. That’s what Google Public DNS provides for
tens of millions of people.
Google Public DNS has become particularly popular for our users
internationally. Today, about 70 percent of its traffic comes from
outside the U.S. We’ve maintained our strong presence in North America,
South America and Europe, and beefed up our presence in Asia. We've also
added entirely new access points to parts of the world where we
previously didn't have Google Public DNS servers, including Australia,
India, Japan and Nigeria.
Shortly after launch, we made a technical
proposal
for how public DNS services can work better with some kinds of
important web hosts (known as content distribution networks, or CDNs)
that have servers all of the world. We came up with a way to pass
information to CDNs so they can send users to nearby servers. Our
proposal, now called “edns-client-subnet,” continues to be discussed by
members of the Internet Engineering Task Force. While we work with the
IETF, other companies have started experimenting with implementing this proposal.
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, 8.8.8.8 and 8.8.4.4.
Google Public DNS’s goal is simple: making the web—really, the whole
Internet!—faster for our users. If you’d like to try it yourself, please
