You could have an IP 192.168.0.1 but not an IP that ends in .0
like 192.168.1.0 since both 192.168.1.255 and 192.168.1.0 are used
for broadcast.
is this a convention or a rule?
Sorry I saw this mail only now.
This is a rule. Actually it is an accident.
We are losing one extra IP for every subnet.
This is due to historical reasons. I wonder it is due to the conflict
between having all 0s or all 1s for the host part of the IP address.
Anyway one should read the history to figure out exactly what
happened.
