How not to set up your DNS (part 9)
Presented in the now-traditional illustrated form:
; sdig ns gcluk.net ns1.gcluk.net. ns2.gcluk.net. ; dig mx web1.gcluk.net @ns1.gcluk.net [...] ;; ANSWER SECTION: web1.gcluk.net. IN A 18.104.22.168 ;; AUTHORITY SECTION: web1.gcluk.net. IN NS .
(TTLs have been omitted for clarity.)
That's an interesting authority record they're returning; somewhat more like a disclaimer of authority record, in fact.
The effects are closely related to what I saw in HowNotToDoDNSVII. In
this case, we first looked up the
A record and found one, but when
we tried to look for an
MX record the completely bogus
stymied our attempts. (Among other problems, there is no
for the '
.', the DNS root.)
