You're in the right direction. If your server doesn't know the answer to a
question (it's not authoritative and the answer isn't in cache), it'll ask
someone else. This may be a root server if no information at all about the
request is cached, or it may be something further down the line. (Maybe it
already has cached the fact that koobera.math.uic.edu is authoritative for
cr.yp.to, but it doesn't know what the mail exchanger is for cr.yp.to. It won't
go to a root server to find out--it'll head straight to koobera.math.uic.edu.)
