According to the Google Code Blog, in their efforts to make the web faster they are offering DNS (Domain Name Services) to the public.So after reading up on this page which helps you configure your server to use Google’s Public DNS I couldn’t find any information for changing the name servers from your website’s current host to Google’s DNS.

In other words, if I have an account hosted with Hostgator I cannot change my DNS to point to Google’s. I have to actually physically own servers and use their DNS.

So till then let us wait and watch when the service will be launched where we will be able to host our domains on Google Server.
