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.”

Well, we said we’d try to keep to a monthly schedule, and we arguably just made it! This episode, number 44, features a special guest: Andrew Sullivan, Matt’s colleague at Dyn and Chair of the Internet Architecture Board. Now, if we’d planned ahead and let you know Andrew was going to be on the show, we could have let you know so that you could have submitted lots of thoughtful questions for him to answer, but by now you know not to expect that kind of forethought from us. Instead, we asked him about stuff we’re interested in, including the IANA transition and ARCING, an IETF effort to identify alternative resolution contexts. We also answer a question from Sheridan West about some suspicious-looking log messages from his name server and one from Jeff Helman about the right DNS configuration for handling multiple back-end web servers.

In this 40th episode–a milestone!–Matt and Cricket answer long-suffering listener Grant Taylor’s question about sorting replies by type and wander into the Land of Happy Eyeballs, then explore an answer Joe Abley received from Mark Andrews of ISC. Meanwhile, a discussion of the term G-job causes Matt to recount accidentally insulting a group of public servants, and both Matt and Cricket discuss their hope that the new AppleTV will lead to the end of their paying for streaming content they could have watched for free.

In this star-studded episode, Matt and Cricket take advantage of a meeting of the DNS Cabal–that is, the annual “Inside Baseball” event–to answer Donald Rudder’s question about whether synthesizing NXDOMAIN responses to avoid random subdomain attacks would work with NSEC3 as well as NSEC records. This is followed by a wildly entertaining (by DNS standards, anyway) discussion of the future of DNS, new TLDs, communication in the event of attacks, and more.
Guest-starring some of the brightest lights in DNS, including Kris Beevers, Brian Brady, David Dagon, Casey Deccio, Rob Fleischman, Olafur Gudmundsson, Shumon Huque, David “Tale” Lawrence, and Duane Wessels.

In this episode, long-time (and likely now sole) listener Yiorgos Adamopoulos asks about the the process of signing the root zone, which Mr. DNS has some experience with. Matt also recaps some of the goings-on at the latest DNS-OARC meeting in Amsterdam, omitting that which must stay in Amsterdam, but revealing some lapses from his DNSSEC RFC-editing days.

In this episode, Matt and Cricket respond to Tommi Nikkilä’s followup to his original question about the legality of multiple CNAME records in a DNS answer, and then react to (to claim they “answer” it is a reach) dedicated listener Yiorgos Adamopoulos’s question about registering domain names with underscores in them. On the way, Matt describes his quest to set a personal record in his commute from his home in Bethesda to Dyn’s headquarters in Manchester, New Hampshire, and then (inadvertently?) disses Cricket’s manhood by suggesting that Real Men Drive with Standard Transmissions. Finally, the guys bemoan their lack of questions, implying that this is somehow responsible for their sporadic production, when we know in fact it’s their own damn fault.

In this episode, Matt and Cricket wonder aloud whether they’ve lost their domestic audience, but then rally to answer questions from their remaining international listeners: Evaggelos Balaskas’s question about SRV records, Joe’s questions about resolver and name server fallback to TCP, and Tommi Nikkilä’s question about multiple CNAME records attached to the same domain name. And, oddly enough, they wrap up with a discussion of the joy of milk delivery.

In this episode, Matt and Cricket answer questions (some posed on Twitter – please welcome Mr. DNS to the 21st Century) from ErrataRob about Verisign’s DNS infrastructure, from devoted listener Yiorgos Adamopoulos on the value of DNS certifications, and from Frederic Cambus about zone file access programs. And you’ll hear some of Matt’s and Cricket’s thoughts on espresso if you stay till the bitter (ha!) end.
