> It is indeed a DNS query for a TXT record:
this is slightly tamer than what i'm going to propose for BIND. i want to
be able to send a specific message saying "CERT VU# xyz" if someone is running
a known-vulnerable version. DNSSEC now makes this practical. but it would
be an information leak, since the version number would be part of the QNAME.
