GOOGLE DNS | GOOGLE DNS IPv6 | GOOGLE DNS IPv4

Google DNS is a free public Domain Name System (DNS) service that is offered to millions of Internet users around the world. The public DNS service and servers that are offered maintained and owned by Google. It functions as a recursive name server providing domain name resolution for any host on the Internet.

Google-Public-DNS

The service was announced on 3rd December 2009, in an effort to make the web surfing faster and more secure. By 2014, Google Public DNS is the largest public DNS service in the world, handling over 400 billion requests per day.

Google DNS services provide efficiency and speed benefits such as

  • Using Anycast routing to send user requests to the closest data center,
  • Over-provisioning servers to handle denial-of-service attacks
  • Load balancing servers using two cache levels with a small per-host cache containing the most popular names and another pool of servers partitioned by the name to be looked up.
