That's a matter of choice for a private network, but the 192.168.x.y
address range is usually treated as /24 networks --- it is in what
used to be the old C class part of the IP space before CIDR became
de-rigeur.
So:
Network number: 192.168.0.0
Netmask: 255.255.255.0 or 0xffffff00 or /24
Broadcast: 192.168.0.255
Which gives you a total of 254 address from 192.168.0.1 to
192.168.0.253 to use for your hosts.
Cheers,
Matthew
