Is this really a problem nowadays?  We have a few address pools that
span a /24 boundary, and we haven't bothered to skip over the .0 and
.255 addresses.  I don't recall ever getting trouble report for any of
these addresses.  Has anyone else on this list run across clients
(recently) that couldn't handle a .0 or .255 address?
