Google Public DNS is the internet giant's first foray into handling these queries.

Advantages of Google Public DNS

Google has outlined several benefits to its experimental service. These include faster page loads, enhanced protection against spoofing attacks and an end to the practice of blocking, filtering or redirecting users.

The information will not be stored in the user's Google account or shared with other Google properties such as Search and AdWords. And it has stated that the browsing data will not be shared with external parties.

Prem Ramaswami, a member of the Google Public DNS team, said: "We believe that a faster DNS infrastructure could significantly improve the browsing experience for all web users. We plan to share what we learn from this experimental rollout of Google Public DNS with the broader web community and other DNS providers to improve the browsing experience."
