That makes no sense ... if a particular host connects to a different
subnet, I'd want it to get the information *appropriate for that subnet*,
not the one where it may have a static IP/reservation/whatever you want to
call it. What am I missing?
I'm with Mr Snyder - it's kind of a pain. I'm only dealing with a /23 and
a dozen or so reservations, but still.
