Thanks, I see what you mean, the master of the tld is also slave
for the domain.tld in question.

As a matter of fact only the tld. master returns aa
 (and 3 NS's for the domain)
One of the slaves for the tld. returns !aa (but 3 NS's)
All others return !aa and 2 NS's

The one that returns !aa + 3 NS's claims to be : bind 8.1.2,
all the others some flavor of 8.2.2.

The master of the tld disallows axfr,
so I cannot see what is in that zone/what the slaves receive.

Thanks a lot,

Marc
