Hi,

I run into an unclear situation while trying to resolve certain domains.
It happened when I tried with 9.7.0rc1, 9.7.0b and also with 9.7.0. I
dont's have a whole lot of other BIND versions at my disposal, but I
found an older one, 9.3.4-P1.2, and that one works fine.

One of the domains that suffers from this issue is www.airfrance.fr. It
gives a SERVFAIL:

; <<>> DiG 9.7.0rc1 <<>> www.airfrance.fr @localhost
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 65377
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;www.airfrance.fr.		IN	A

;; Query time: 1 msec
;; SERVER: 127.0.0.1#53(127.0.0.1)
;; WHEN: Fri Feb 19 19:03:35 2010
;; MSG SIZE  rcvd: 34


Anyone any clue? I am trying to understand why some resolvers handle
this query well, while BIND 9.7.x returns a SERVFAIL.

dig +trace www.airfrance.fr works as expected.

logging says:

lame-servers: info: lame server resolving 'www.airfrance.fr' (in
'www.airfrance.fr'?): 193.57.219.253#53

Thank you.

Regards,
