Thirty years ago this month, in November 1983, two RFCs were published that defined the criticalInternet service that we now take for granted and use every day – the Domain Name System or more generally just “DNS”. Those two RFCs, authored by Paul Mockapetris, were: · RFC 882: Domain Names – Concepts and Facilities · RFC 883: Domain Names – Implementation and Specification These two RFCs formed the basis for what was to become the DNS system we use today. There was a great amount of discussion in the early 1980′s around how to move beyond the flat naming convention used in the early “ARPA Internet”. Several proposals were out there that make for interesting reading today, including RFC 799, RFC 819 and RFC 830. As Paul Mockapetris relays in a video for the Internet Hall of Fame (IHOF) Internet timeline, his boss at the time, Jon Postel, asked Paul to look at the various ideas and come up with a proposal of his own for how it should work. The result was RFCs 882 and 883. Four years later, in November 1987, these two original RFCs (882 and 883) were then “obsoleted” by RFC 1034 and RFC 1035 in which Paul updated and expanded the original RFCs based on the experience of those four years in actually implementing DNS. These newer RFCs 1034 and 1035 are still the basis of DNS today, although they have been “updated” many times since, including by the addition of DNSSEC in RFCs 4033, 4034 and 4035. Today the DNS is a critical part of our Internet infrastructure and is the serviceguiding us in connecting to all the other services we use across the Internet. We all use DNS all the time every day even though, as Paul Mockapetris wrote earlier this year, we may not even be aware thatwe are using DNS.
