What is DNS?

The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. In short, it translates machine or server IP to URL that we see and type in the browser and vice-versa. We humans do not like numbers and that’s why it can take a lot of mind-crunching moments to remember one, on the other hand we love remembering short phrase  or clusters of words and this way Computer Scientists managed to invent DNS.

In the early days, i.e. before DNS is invented in 1982, every computer on the network included a HOSTS.TXT file is retrieval from a computer at SRI.There are corresponding fields that maps the names to numerical addresses for example the local host is mapped to 127.0.0.1. But the rapid growth of computer network made the manual handling of the file impossible and this lead to the invention of Domain Name System in 1983 by Paul Mockapetris. He was the first guy to implementation the first working version of Domain Name System.
