To clarify, it's sometimes necessary to "mix" iterative and recursive
resolution in the same nameserver instance, maybe even the same view.
Oftentimes, there simply is no choice, because the source of the zone
information doesn't make an authoritative nameserver available, only a
forwarder (thus the insidious, viral effect of forwarding; forcing not
only your own infrastructure into recursive resolution, but that of
everyone who wants to talk to you as well, ultimately culminating in a
spiderweb of point-to-point dependencies).
What I meant by "mixing" (possibly not the best word choice) is choosing
a recursive option if an iterative option is available, all other things
being equal. Perhaps it would have been better for me to merely promote
"stub" or "static-stub" as an iterative alternative to forwarding, than
to complain about "mixing".

Is that enough?
Understanding the pros and cons of iterative versus recursive
resolution is one of the few things still separating us from the MCSE
savages...

Ugh, that mixes apples (recursive resolution) and oranges (iterative

Out of curiosity, what bad thing do you think will happen if you mix
these two functions?
