i'm not sure what we're talking about.

there has to be more than one reply to a given ip address for each
*response* you are thinking of sending. definitely more than one, to
account for multiple outstanding queries, recursives behind NAT, and
postel's robustness principle.

but it's *responses*, not *queries*, that you have to be aware of.
