Before the development of the [[DNS]], information about hosts was assigned in a flat namespace format and name-to-address lookups were done using a table, which use to be available in all the hosts. Network Information Centre (NIC) at [[SRI International]], use to maintain this table and all hosts get the updated copy from SRI-NIC periodically. At that time, most of the hosts were at [[ARPANET]] (Advanced Research Project Agency Network) and [[DND]] (Defense Data Network), and managing the host records in a flat file wasn’t that tough. <ref>[https://marc.info/?l=namedroppers&m=95837667426588&w=2]</ref><ref>[https://www.donelan.com/dnstimeline.html DNS Timeline, Donelan]</ref>

As the number of hosts were increasing so was the size of this flat file, and with the frequency of updates, a decentralized database need was felt. To address this problem, Mr. [[Jon Postel]] and Mr. [[Paul Mockapetris]] published a number of RFCs that laid down the design of DNS.
