A simple question ...
Is it legal for a nameserver to ever flag a response with "AA" when it is not
authoritative for a zone?
I notice windows nameservers who permit recursion will flag a response with
"AA" (fetched from the authoritative server) the first time the lookup is
done. Afterwards, when just fetching from it's cache, it does not.
Bind never does this.
Is one incorrect, or is this just a permitted difference in implementation? I
can't find any reference in the RFC's ...
It seems to me ridiculous for a server to flag AA unless it actually does
answer for the zone in question ...
