I have had just the opposite experience; my local LAN is w.x.48.0/20 , and so
I have 15 perfectly good w.x.y.0 and w.x.y.255 addresses other than the
wire/broadcast addresses. I have assigned most of them to a variety of machines,
and so far the only grok-failure came from Windows95 boxen, which dislike
w.x.y.255 . This is not altogether surprising, given MS's notable proficiency
in networking...

Yes, it could be, actually. I tried to use it as WAN pool address once
though and it horrendously confused the RAS, as well as several UNIX boxen
on the network.
