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 36

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.

Episode 35

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.

Episode 34

In this episode, Matt and Cricket answer Harry Stein’s question about a DNSstuff search that turned up suspected cache poisoning, and Kirk Davis’s question about Google’s (somewhat crazy) recommendations on how to force the use their non-SSL-based services.

Episode 33

Here, at long last, is Episode 33, in which Matt announces a “Development with a capital D” (and a lowercase “yn”), and Matt and Cricket answer questions from Jason Weber about how to deal with web hosting and a hosted DNS zone; from Chuck Nelis about split DNS; from Michael Simoni about the (waning?) need for multiple zones; and from Matt Pounsett about the dangers of mixing recursion and authority on a single name server.

Episode 32

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.

Episode 31

In this, their inaugural episode for 2013, Cricket and Matt answer a question from the mysterious “Joe” (if that is his real name) about the differences between BIND’s stub zone and conditional forwarding features, prompting some reminiscing about the good old days of BIND 8.  This episode is the third in which we tackle questions from apparent long-time listener Yiorgos Adamopoulos, who wonders about the various features of dig and if Mr. DNS still writes code.

Episode 30

In this latest episode of our evidently-now-quarterly podcast, Matt and Cricket answer Donald Rudder’s question about how common the A6 record is and its effect on DNSSEC.  Then they discuss the upcoming change of d.root-servers.net’s IPv4 address and the implications of that change.  And despite having only one question to answer, they manage to take up the usual 30 minutes!

Episode 29

In this episode, Matt and Cricket finally throw in the towel and give up on promising podcasts on any regular schedule.  But they do manage to clear Mr. DNS’s mailbag, answering questions from Ismael Lezcano about the availability of good programming APIs for working with DNS and why BIND doesn’t have a good mechanism for creating and deleting zones dynamically; and from William Brown  about how to induce major registrars to support DNSSEC.

Episode 28

In this (much delayed) episode, Matt and Cricket discuss the folly of trying to hew to a podcast-publishing schedule, and answer (or avoid) questions from Sevan Janiyan and Yiorgos Adamopoulos on what operating systems and software the root name servers run; from Kent Shuey on why a device that implements only part of the DNS specs seems to work okay on his network; and from Todd Larsen (apparently of Danish descent) on where he can go to meet like-minded souls discussing current issues with DNS and DNSSEC (God help him) and whether DANE’s TLSA record can coexist with a CNAME record.

Episode 27

In this episode, Matt and Cricket answer Alan Frabutt’s question about the existence of recursive name servers that don’t honor TTLs – the “yeti” of recursive name servers – and Joe Conlin’s question about the right way to deal with abuse of your name server, and try to assist Louis Sterchi in his quest to learn more about DNS, registries and registrars.  And this last leads them on a trip down the Internet’s memory lane, reminiscing about the old days of DNS, before registries and registrars, back when subdomains of com, net and org were free.
