DNS (or Domain Name Servers) is basically a system to convert domain names into IP addresses. Domain names are easier to understand, memorize and write for humans while computers only use IP addresses to communicate.

Normally, the ISPs provide their users with their own default DNS server IPs which are often unreliable and slow. There are many better, faster, safer and more reliable public DNS servers for your everyday use. Here is a list of all such fast & free public DNS servers along with their IPs.
