Not BIND-related specifically... (though the server below could be running BIND I suppose).
This seems weird. Why is this authoritative server returning *some* answers with decrementing TTL's? $ dig @ns1.dtra.mil dtra.mil NS ; <<>> DiG 9.7.4-P1-RedHat-9.7.4-2.P1.fc14 <<>> @ns1.dtra.mil dtra.mil NS ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 34658 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;dtra.mil.

Odd.
