How not to set up your DNS (part 13)

December 7, 2006

In the traditional illustrated format:

; sdig ns
; dig mx

;; flags: qr aa rd; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0
. 1 IN SOA . ...

That's an interestingly grandiose claim of authority is making there. (And also an interesting primary nameserver they claim the DNS root has.)

For bonus points, they actually return an A record for, although without the usual authority records that you'd expect. It's just queries for other records that they fail. I'm left wondering if the nameservers are actually some species of caching nameservers, and bits have fallen out of their caches and haven't been refreshed.

(Given everything else, we probably didn't want to get email from a domain called '' anyways.)
