IP Addresses
If you are uncertain about what IP addresses to assign your equipment,
contact your network administrator.
To operate correctly, each device on your network (for example a hub
or management station) must have a unique IP address (if one is
configured). IP addresses have the format
n.n.n.n where n is a decimal
number between 0 and 255. An example IP address is ‘191.1.1.8’.
The IP address can be split into two parts:
■
The first part (‘191.1’ in the example) identifies the network on
which the device resides.
■
The second part (‘1.8’ in the example) identifies the device within
the network.
If your network is internal to your organization only, you may use any
arbitrary IP address. We suggest you use addresses in the series
191.1.1.
X where X is a number between 1 and 254. Use the default
SLIP address of 192.168.101.1.
If your network has a connection to the external IP network, you must
apply for a registered IP address. This system ensures that every IP
address used is unique; if you do not have a registered IP address, you
may be using an identical address to someone else and your network
will not operate correctly.
