DNS Celebrates Its 20th Birthday

Nominum, a pioneering provider of IP address infrastructure software, is commemorating the 20th anniversary of the invention of the domain name system (DNS). Dr. Paul Mockapetris, the company's chief scientist and chairman, developed the protocol that all Internet users depend on for sending email and locating web resources. The first use of the DNS took place on June 23, 1983 at the University of Southern California School of Engineering's Information Sciences Institute (ISI). Dr. Mockapetris is now working towards the next generation of the DNS to accommodate the growth of IP computing and future applications, such as IP telephony and radio frequency identification (RFID) tags, that will depend on the system.

In 1983, Dr. Mockapetris and the late Dr. Jonathan Postel, director of the Computer Networks division at ISI, recognized the need for a global database of computer names and collaborated on the system as part of a pre-Internet project. Twenty years after its invention, DNS is essential to the Internet. All Internet users depend on DNS every time they access a web URL or send an e-mail message, because the system translates words into the numbers needed to locate Internet resources.

As the world's largest and busiest distributed database, the DNS handles billions of requests every day and was the first proof that database replication could be invisible and reliable on a global scale. With every e-mail message sent or URL viewed, a request is made to multiple name servers scattered all over the globe. Today, enterprises depend on Dr. Mockapetris' invention to keep their online business operations running without interruption. Without DNS, the Internet would shut down very quickly.

"A billion users will touch the DNS this year, and some won't even know it because they simply placed an internet phone call or looked at a Web page, or bought a package with an RFID tag, and the growth in its usage will continue to be explosive," noted Dr. Mockapetris. "In the next five years, I expect to see a dramatic increase in the number of ways in which the DNS is used, reaching far beyond what we have seen in the past twenty."

Dr. Mockapetris was honored with this year's prestigious IEEE (Institute of Electrical and Electronics Engineers) Internet Award for his invention of the DNS in collaboration with the late Dr. Postel. As a visiting scholar at the Postel Center, established by the Information Sciences Institute of the University of Southern California, Dr. Mockapetris is currently experimenting on future applications for the DNS. His decision to join Nominum in 1999 marked Dr. Mockapetris's renewed focus on DNS and IP addressing and the potential it holds for the future of the Internet.
