[dnsop] Another example of AAAA misbehavior

["Barber, Piet" <[e-mail]>]

Although servfail rcodes have already been mentioned in this draft, I 
would like to add this nice little gem of DNS. This name server responds 
to AAAA queries in a particularly odd way:

1) 'aa' bit + SERVFAIL.
2) Reflexive CNAME.
3) answer section given, despite the SERVFAIL

dig @ns.intouch.net ns.intouch.net aaaa +norecurs

; <<>> DiG 9.2.1 <<>> @ns.intouch.net ns.intouch.net aaaa +norecurs
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 58716
;; flags: qr aa; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;ns.intouch.net.                        IN      AAAA

;; ANSWER SECTION:
ns.intouch.net.         3600    IN      CNAME   blade230.intouch.net.
blade230.intouch.net.   3600    IN      CNAME   blade230.intouch.net.

;; Query time: 92 msec
;; SERVER: 212.26.192.1#53(ns.intouch.net)
;; WHEN: Wed Mar 24 16:17:16 2004
;; MSG SIZE  rcvd: 69
