So basically DNS is essentially providing that same service to computers.
Paul Mockapetris originally designed DNS at the University of California, Irvine in 1983 but many others have helped in the development of DNS to make it what it is today. Before that a protocol name Advanced Research Projects Agency Network (ARPANET) was being used but a rapid growth of networks required a new system for maintaining the host names and addresses. ARPNET was created by Dr. Jon Postel. In 1984, a couple UC Berkeley students wrote the first Unix name server implementation. It was called the Berkeley Internet Name Domain (BIND) Server. In 1985 it was revised and has since been then it has been a widely distributed mostly on Unix systems, and which is still the most widely used DNS software on the Internet.
Before I go into more details about DNS, I will go through a quick run through on how to install DNS. It is actually pretty simple to install/configure DNS but you need to make sure you have the prerequisites installed before DNS can be setup. Installing a DNS server involves adding the DNS server role to an…
