Actually, x.32 to x.63, with x.32 being the network address. My personal opinion, if you're using RFC1918 addresses for internal networks, you should only use 255.255.255.0 netmasks everywhere, even though it's a network for one machine only. Dealing with netmasks is a PITA, and should be avoided unless there's a real reason to use it, for instance with valid IPs.
