The Domain Name System (DNS) was created in 1983 by Paul Mockapetris, an American computer scientist. This system replaced the prior method of identifying computers on a network, which was a simple text file.
The first domain name ever registered was "symbolics.com" on March 15, 1985. It was registered by the Symbolics Computer Corporation, a computer manufacturer.
Domain names can be up to 63 characters long, not including the domain extension (.com, .org, .net, etc.) and the total URL can be up to 255 characters long.
