First of all what is DNS?
DNS stands for Domain Name System. It is an Internet service that translates domain names or host name into IP address. Our machine does not understand Host names, they identify websites using IP address. When u enter a website name in URL bar of your browser the browser sends the request to a DNS server to resolve the website name and it returns a IP address.When IP address of website is received browser contacts the IP address and displays the Website. For eg: www.google.com might be translated to 220.127.116.11. Now you might have understood what are DNS so lets move a step ahead and discuss whats is DNS server. A DNS server is a dedicated machine or server or a service within a machine that provides name resolution in an IP network. It changes names of websites and other network resources to numeric IP addresses.

Example if you are using Airtel, TMobile, or MTNL broadband connection they provide their private DNS servers. It means a MTNL user cannot use Airtel DNS servers. But there are some DNS server available on the net that provide DNS resolution to anyone who requests it to them. These are called public DNS servers. These servers are used by people for faster and safer browsing. You can use these servers as an alternative to your private DNS servers.Some public DNS servers are
