Here's a simple piece of input. If BIND 8.1.1 receives a DNS query
response with an invalid query ID, it logs it and drops the packet.
However, the invalid query ID is evidence of an attack in progress. Why

(in a response-forged query-ID guessing situation). BIND doesn't do
anything about this. Why?
Just the simplest suggestion I can come up with (without having this go
