IETF 108: Technology Deep Dive on DNS

Everyone understands how the Domain Name System (DNS) works, but everyone is wrong! This session was held at 1800 UTC on 23 July 2020.

During this Technology Deep Dive on the DNS you will learn just how wrong you are. This session covered the lesser understood aspects of DNS, and where the sharp edges are.

This session is especially valuable for those who think that they understand how the DNS works, as well as those who want to build something on top of the DNS.
