Nov 14, 2019 · At the 2019 NamesCon conference, I had the opportunity to sit down with Dr. Paul Mockapetris, who invented the Domain Name System (DNS) architecture back in 1983. He provided insights on how the DNS system came to be, and how it continues to evolve. Dr. Paul Mockapetris photographed at the time of the interview at NamesCon 2019.
