what is work of dns




Answer Posted / alf55

The idea of the "dns" dates back to "The NIC Name Server--A
Datagram Based Information Utility" (rfc #756) from July 1979.

Sorry, well before Bill Gates.

But the major implementation was BIND (November 1983)
(meaning is "Berkeley Internet Name Domain" written for
Unix),also be any Microsoft software was network aware.

The purpose is much like a phone book where it takes a
"name" (properly formatted) and turns it into an IP ADDRESS
(which works like a phone number to the computer). The
computer really looks more like a PBX system as the "port
number" is then route to the service being requested.
