Hi Craig, In my opinion, the RD flag has no value in a response really. It's just a way for a client to signal to a server that it wants the server to perform recursive queries. While RFC 1035 requires the server to copy the value of RD from the query into the response, a client shouldn't even be bothering to look at RD in a response, and certainly should not break if its value in the response doesn't match the query.
