Google has introduced its Public DNS and invites users to test it and give feedback on it. For those who are not familiar with DNS we can say that it converts the web address into easy to remember equivalent domain names which are used by computers to communicate with each other for example DNS converts www.google.com into unique Internet Protocol (IP) e.g. 71.105.45.100.


According to Google official blog:

The average Internet user ends up performing hundreds of DNS lookups each day, and some complex pages require multiple DNS lookups before they start loading. This can slow down the browsing experience. Our research has shown that speed matters to Internet users, so over the past several months our engineers have been working to make improvements to our public DNS resolver to make users’ web-surfing experiences faster, safer and more reliable.
