On June 23, 1983, “Paul Mockapetris and Jon Postel ran the first successful test of the distributed Domain Name System (DNS). This automated process was to take over failing Arpanet and CSnet protocols because those relied on address books.
DNS uses a hierarchical distributed naming system for the Internet or any private network. It associates the domain names with numerical IP addresses.”
