Meet Paul Mockapetris. He may not be an industry celebrity like Bill Gates, Michael Dell, Richard Stallman, Eric Raymond, or Linus Torvalds, but he should be. Mockapetris was a key figure in the development of the Domain Name System, the Internet protocol that maps domain names like zdnet.com to IP addresses like 206.16.6.208. Without a protocol like DNS, people, software, and computers would be cast adrift in a sea of incomprehensible and changing numbers. Although others were involved with the development of the DNS, Mockapetris wrote the protocol, and for this contribution he was recently awarded the prestigious IEEE Internet Award.
