Building Your Own IP Addressing Scheme
If your network is isolated and will not be connected to any other networks
that use IP addressing, you can build your own IP addressing scheme (locally
administered addresses). If you use your own addressing scheme, be aware
that any connection to another IP network could cause communication
problems on both networks. The IP addresses on the two networks must be
compatible. Each address must be unique.
The following documents have detailed descriptions on how to build your own
IP addressing scheme:

Example Addressing Scheme
On the next page is an example of a class C addressing scheme. Class C
addresses allow up to 254 devices to be configured. If you have 254 or fewer
devices to be managed on your network, you can use the addressing scheme
shown below. If you have more than 254 devices to configure, see the refer-
enced documents and use a class B addressing scheme. Class B allows 65534
devices to be configured.
The IP address format is X.X.X.X, where each X is an integer between 1 and
255. The integers are separated by decimal points. For a given network with
its own class C addressing scheme, the first three integers of each address
must be the same. The fourth integer must be unique for each addressed
device. Do not use 0 or 255 as the value in the last position on the right.
They are reserved integers.
For three hubs and an HP network management station on the network, the
class C addresses might be:
The IP Configuration function in the HP Stack Manager software enables
you to specify IP addresses. See chapter 2, “Graphical Software”, and the
software’s online help system for details.
