Back in December 2009 Google launched its Google Public DNS a free, global Domain Name System (DNS) resolution service. But today Google’s DNS service is now longer an experimental service, and has become the worlds largest DNS service.
An Internet DNS service acts like a giant phone book allowing users to look up hundreds or thousands of entries everyday, and now Google’s DNS service is processing over 70 billion requests on a daily basis.
Google Public DNS service is particularly popular internationally, with around 70 percent of its traffic arriving from outside the U.S. Google also has a strong presence in North America, South America and Europe, and increased its presence in Asia. As well as adding new access points to parts of the world that previously didn’t have Google Public DNS servers installed, including Australia, India, Japan and Nigeria. You can find more information about Google DNS service over on the official website here.
“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.
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 see our page Using Google Public DNS. For more information, please see our Introduction to Google Public DNS and Frequently Asked Questions.”
