Episode 46

The Ask Mr. DNS Podcast

This episode, number 46, features a guest appearance from Roy Arends of ICANN, whom Matt, Roy’s boss, swears wasn’t forced to participate in our forsaken podcast after midnight Oxford time. Roy’s worked on Unbound, fpdns, DNSSEC, and Nominet’s Turing product. We answer questions from Jacob Evans about mismatched SOA records and name server support for IPv6 anycast, and from long-suffering listener Evaggelos Balaskas about Response Policy Zones and why he sees different responses to queries for A records for google.com. Along the way, Matt announces his new job, and while tracing the origin of Matt’s pet phrase, “There has been no time,” a discussion of the term “shirt-tail relatives” ensues, during which Cricket forgets the word “commutativity.”
