The bits of the subnet mask are set to 1 if the device
should treat the corresponding bit in the IP address
as part of the original network number or as part of
the subnet number. These bits in the mask are set to
0 if the device should treat the bit as part of the
device number, as shown in Figure B-1 .

CAUTION: To ensure that Quick Config Manager can
always communicate with the hub, the IP subnet
192.168.101.x is permanently assigned to the SLIP
port in addition to the user configurable SLIP
address. Do not use this subnet for your Ethernet

(network).

Assigning IP Addresses to a Small, Contained

Network
If you have a small network (less than 255 devices)
that you do not plan to connect to the Internet then
here is a guide as to what you can use for the IP
addresses and subnet mask:
Use an IP address that is in the range 192.000.001.xxx
to 223.255.254.xxx (Class C) to define your network,
and allocate device numbers (the xxx part of the IP
address), starting from 1.
Use a dummy subnet mask of 255.255.255.0 to
match the network portion of your IP addresses.
Remember that no two devices on a network may
have the same IP address.
