Paul Mockapetris

Paul Mockapetris expanded the Internet beyond its academic origins by inventing the Domain Name System (DNS) in 1983. At the University of Southern California’s Information Sciences Institute, Paul Mockapetris recognized the problems with the early Internet (then ARPAnet)’s system of holding name to address translations in a single table on a single host (HOSTS.TXT). Instead, he proposed a distributed and dynamic naming system, essentially the DNS of today. Read his full bio here.
