In this, our holiday episode, we’re joined by returning special guest, Duane Wessels, who discusses a recent event involving the root name servers and a lot of obviously spoofed traffic, as well as his ongoing work in the IETF around DNS privacy. We reach into the mail bag and find a question from our friend, Rob Fleischman, musing about possible additional metadata that recursive servers could send to authoritative servers. As it happens, Duane’s also working on a DNS protocol extension directly related to Rob’s question, which he tells us about. Finally, we end with a brief and spoiler-free discussion about The Force Awakens.

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, 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.
