Thanks for this great reference. I think it will make my situation better
than it has been, but it won't work for me as a "cookbook" solution (which I
confess I need), since the examples there are of small "blocks", whereas I
have a discontinuous group of a dozen IPs spread from 17. to 196. Am I just
banging my head against the wall for nothing, or is it possible to make a
viable sub-domain out of discontinuous IPs? The idea of Michael Kukat seemed
to be just the ticket.  (Actually, I just went ahead and tried it, and so
far it hasn't brought the whole lan down!)
