.255 addresses still not usable after all these years?

I remember back in the day of old hardware and operating
systems we'd intentionally avoid using .255 IP addresses
for anything even when the netmask on our side would have
made it fine, so I just thought I'd try it out for kicks
today.  From two of four ISP's it worked fine, from Verizon
FIOS and Road Runner commercial, it didn't.  So I guess
that old problem still lingers?
