Episode 58

Another year brings another Inside Baseball event, where an ad hoc group of DNS industry insiders get together for a day to talk about current issues and then go to a baseball game (really). So many DNS-knowledgeable folks in one place had the makings of a great podcast episode, so we got out the recording gear and dived into the mailbag to answer four questions. In addition to Cricket and Matt, you’ll also hear Alex Dupuy, Dave Lawrence, Matt Pounsett, Rob Seastrom and John Todd.

Episode 57

…in which Matt and Cricket, in a cunning bit of Tom Sawyering, take Rob Fleischman’s question about how recursive DNS servers handle TTLs of zero, and induce Rob to both a) join the podcast as a guest and 2) paint their fence by doing all the legwork to find the answer.  In the inevitable light banter segment at the end of the episode, Cricket highly recommends Taika Waititi’s What We Do in the Shadows, likely the funniest vampire mockumentary ever made.

Episode 56

We’re back with an emergency episode published just in time to inform your frantic preparations for DNS Flag Day on 1 February 2019. We’re delighted to welcome another special guest, Petr Špaček from CZ.NIC, to fill us in and let us know if we should stockpile food for an impending Internet collapse and the ensuing end of civilization as we know it. Or maybe it’s just the story of a few DNS developers whose patience has finally run out. Then Matt recommends the Netflix show Babylon Berlin, and Cricket and Matt lament their years-long study of German with not nearly as much to show for it as we’d like.

Episode 55

We’re back after our longest hiatus yet. Alas, the mail bag was empty, so instead we invited special guest Paul Hoffman to talk about DNS over HTTPS (DoH), which has generated some buzz in the DNS community (to the extent that anything can generate buzz in the DNS community). We end with our usual pop culture consumption recap, this time focusing on what we’ve read recently (science fiction, unsurprisingly) and what shows we’ve watched in this new Golden Age of Television.

Episode 52

In this episode, number 52 (cards in a deck! And just wait till we hit 53, which has special significance!), Matt and Cricket are joined by a pantheon of the gods of DNS.  However, since they neglected to ask any of the speakers to introduce themselves, you’ll just have to guess, Band Aid “Do They Know It’s Christmas”-style, who’s who.  (Olafur’s basically a gimme–our Boy George or Bono.)  We answer David Mar’s question about how to learn the basics of DNS and then recap some of the topics of the Inside Baseball meeting we’d been attending, graciously hosted by Salesforce and organized by Allison Mankin & company.

Episode 49

Cricket and Matt took advantage of being in the same place for once to record the podcast, though that doesn’t stop us from forgetting which episode number we’re actually recording.  We answer four questions on subjects relating to SPF, DNSSEC, /etc/host.conf and authoritative server selection by recursive name servers.  On that last topic, Matt refers to research on server selection he contributed to and promised a link to the paper in the show notes.  The paper is “Authority Server Selection of DNS Caching Resolvers” and was published in ACM SIGCOMM Computer Communication Review (CCR), April 2012.

Episode 48

In Episode 48, we are pleased to welcome Bert Hubert of PowerDNS fame to the show.  We reach into the mailbag to answer Nic Waller’s question about measuring which names in a zone are actually queried, Jesus Cea asked about proving domain ownership to obtain a Let’s Encrypt certificate (which caused us to do some actual research before recording!), and long-suffering listener Yiorgos Adamopoulos gamely sent in a question about using the block chain for name resolution.  As usual, we indulge in light banter completely unrelated to DNS, this time on outrageous cell phone roaming charges and Dutch pipe organs.

Episode 47

In this episode, our 47th, we realize the mailbag is actually fuller than we thought, and work diligently to answer questions from a “long-term” Swedish listener about IPv6 reverse mapping, from Jeremy Laidman about BIND 9.11′s new catalog zones feature, and from (the also likely Swedish) Håkan Lindqvist about the credibility of DNS data, particularly NS records.  We also digress into ruminating over the possible deleterious effects of The Disney Channel on the attitudes of tween daughters, why the first four minutes of the forthcoming “Sully” are likely the highlight of the film, and what we’ve been watching on TV lately.  Don’t miss it!

Episode 45

We’re back again, scraping the bottom of the mailbag for questions.  Erik Radde helped us out with a question on the interaction of wildcards and the search list, and Lenny Tropiano tweeted a question at Mr. DNS about Dyn’s support for a feature that provides CNAME-like semantics at a zone apex.  Along the way there were detours into the three laws of thermodynamics and, more importantly as the AI revolution grows ever closer, the three laws of robotics.

Episode 44

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.
