DNS enables users to reach their destination websites. It translates the commonly known domain names into their respective IP addresses in order to locate and identify computer services and devices with the underlying network protocols. DNS is of prime importance and has been used since the 80s. So, the basic idea is that Domain Name System is analogous to a phone directory.
