What is DNS?
The Internet is a network which is known to connect millions of computers across the world. Some computers on this network are turned on around the clock-servers with email and websites. When you connect to the Internet, each computer is assigned a special numeric identifier – the so-called ip address. However, it is not very convenient for people to access the servers using it, so letter domains were introduced.
DNS is a system that ensures that all domains match IP addresses. A special class of servers called ns servers is responsible for storing DNS records on the Internet. Some of them are supported by domain zone administrators, others-by Cheap Hosting India service providers and hosters.
