Xante 3 Series warranty Reserved IP Addresses, Network Masks, Be used as a device address

Note: The actual number of usable host IDs is smaller than the calculated number listed above, because some addresses are reserved, by convention, for specific uses. See the list in the next section, “Reserved IP Addresses.”

Reserved IP Addresses

The addresses in the following table are reserved, by convention, and

should	not	be used as a device address.
		Reserved IP Addresses
	Net ID	Host ID	Meaning
	all 0’s	all 0’s	This host
	all 0’s	host ID	A host on this network
	all 1’s	all 1’s	Limited broadcast (local network)
	net ID	all 1’s	Directed broadcast (network specific)
	net ID	all 0’s	Network address
	127	anything	Loopback address
			(should	never appear on a network)

Addresses not shown in the preceding table should be valid, as long as they identify the host within the given network. See your System Supervisor for the correct address to use.

Network Masks

The server uses a network mask to identify all workstations on the same network. In the absence of subnetting, the network mask is created by using 255 (all 1s) for the network ID address octets and by using 0 for the host ID octets.

On a class C network	, the network mask is	255.255.255.0
On a class B network	, the network mask is	255.255.0.0
On a class A network	, the network mask is	255.0.0.0
