What is DNS?
DNS is short for Domain Name System. It functions as the internet’s version of a phone book, converting difficult-to-remember IP addresses into simple names. Cheaper technology and the introduction of desktop computers in the early 1980s facilitated the rapid development of local area networks (LANs). As the number of machines on the network grew, it became impossible to keep track of all the different IP addresses.
The development of the Domain Name System (DNS) in 1983 solved this problem. DNS was invented at the University of Southern California by Paul Mockapetris and Jon Postel. It was one of the breakthrough inventions that helped in paving the way for the World Wide Web.
