Do you have a question for Mr. DNS?

If you have a question about DNS for Mr. DNS, he’d love to hear it. Drop him a line at mrdns@ask-mrdns.com.

Episode 61

In this episode, Matt and Cricket are joined by Kim Davies of ICANN and PTI (you’ll have to tune in to find out what that stands for).  Kim edifies us on key ceremonies and the Herculean efforts required to keep a key ceremony secure and transparent during what Matt referred to as a “global pandemic,” immediately regretting his use of the redundant phrase.  Later, Cricket is embarrassed to learn that Matt has already read both of the new books he’s reading (John Scalzi’s “The Last Emperox” and Martha Wells’s latest in the Murderbot series, “Network Effect“), and Kim laments that the end of business travel leaves him with no time to watch anything.  Oh, and the guys (or Matt, really) answer a really good question from Swapneel Patnekar about an ICANN paper on the effects of COVID-19 on the root name servers.

If you’ve already listened to the episode and are interested in the resources Kim referred to, here are the links:

Episode 60

We’re back with special guest Joe Abley, CTO of PIR, the registry for .ORG. We talk DNSSEC, research ideas, and more. Sadly, the mail bag was empty, but we still found more to talk about: DNS Flag Day 2020 is proposed to reduce fragmentation of DNS messages sent over UDP. Then Admiral Picard made an appearance, or was at least discussed. Finally, we urgently request your DNS questions at mrdns@ask-mrdns.com to fill the mail bag!

Episode 59

In this episode, Matt and Cricket are joined by Cricket’s recent co-author, John Belamaric, to discuss CoreDNS, a DNS server built to act as a service discovery engine in containerized environments, particularly those managed by the ubiquitous Kubernetes.  They also answer a question from Shane Kerr about why certain RR types insist on using canonical names in RDATA, and Cricket expresses his displeasure at the mispronunciation of “bailiwick.” Finally, they discuss “The Mandalorian,” and Cricket once again strongly recommends Taika Waititi’s movies, especially “What We Do in the Shadows” and “Jojo Rabbit.”

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 54?

Was it Cricket Liu Live or Ask Mr. DNS Live?  And does it really matter?

Shortly after the first anniversary of the massive DDoS attack on Dyn, Matt and Cricket broadcast a session on DDoS attacks and their relationship to DNS from the National Press Club in Washington, D.C.  They talked about how DDoS attacks target DNS infrastructure, how those attacks can exploit name servers, and recapped last year’s attack.  And they even examined some mechanisms that will help protect your DNS infrastructure from DDoS attacks:

Episode 53

This isn’t exactly an episode, but Matt and Cricket recently recorded a short promo for Infoblox’s DNS Awareness Day campaign, and they decided to keep recording because Cricket wanted to hear about the recent DNSSEC Key Ceremony, in which Matt had served as the Ceremony Administrator.  So if you’re curious about how new root keys are generated and the sort of security that’s involved, tune in!

Oh, and there’s video, for the first time!

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.
