Why was the Internet's Domain Name System (DNS) created?
What will be an ideal response?
With a name server on a network, all one needed to know to communicate with a resource was the name server's IP address and the resource name. This method worked for local networks, but new problems emerged when dealing with resources on the Internet. For instance, if every computer on the Internet had resource information (also known as a resource record) stored on one name server, you can imagine how difficult it would be to sift through these records to find the one resource you're looking for. Management also becomes a problem. To manage the Internet, it's important to know which entity is responsible for which information. To address these problems, Domain Name System was developed.
