Appendices : Device Configuration : Using reserved IP addresses for private IP addressing

Using reserved IP addresses for private IP addressing
The OnBoard appliance administrator should assign a private IP address to each connected device from one of the three IP Internet address ranges that are reserved for use on internal networks Table D.8 shows the reserved IP address ranges for internal networks.
192.168.0.0—192.168.255.255
172.16.0.0—172.31.255.255
10.0.0.0—10.255.255.255
See http://www.rhebus.com/techinfo/iprange.htm#ip1 for recommendations about which ranges to use for various sizes of organizations and for avoiding address conflicts.
The number of IP address available on a network may be restricted by a subnet mask. For a simple example, the subnet mask 255.255.255.0 provides 256 IP addresses. The IP address ending with zero (0) is the network address, and the IP address ending with 255 is the broadcast address, leaving 254 addresses to assign to devices (from 1-254).
To specify a range of addresses on the Cyclades OnBoard Service Processor Manager supply the network address and a subnet mask, in either of these two formats: 192.168.0.0 and 255.255.255.0
or 192.168.0.0/24.
