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.
