Ok, some type of use like that would make sense. But it's still bad

plus you get 3 nifty special-function IP addresses at no extra
charge!"
Well they are only being honest. To give you your own subnet you do
have to have these other 3 special ip addresses. There's no real way
around that if you want to keep it as a real subnet that's independently
addressable. So they do have to assign you 8 ip addresses total, of
which you can use 5 for anything.
I understand the broadcast address (send to broadcast, your 5 IP's get
the traffic), and I think I see why a gateway address could be needed
in your same subnet (if the IP isn't in your local /29 subnet, then
send it to the gateway IP, guaranteed to be on the same ethernet link
for routing). Could you explain the "network address" concept to me?
I don't get that one.
I'll have to do more research on this particular concept. My hunch is
that it has to do with routing traffic into the subnet. But I am not sure.
