3. For stand-alone local area networks, RFC 1597 provides for three address ranges so that
10.0.0.0
172.16.0.0
192.168.0.0
The IP addresses for small networks should be selected from these ranges.
Company network
Since the company network already exists, you will need to ask the administrator for the
settings and addresses.
A fixed IP address is used to address the company network. You will need to ask your
administrator for an IP address for each NCU.
The computer name is also provided by the network administrator and corresponds to the IP
address that is set.
Further, it is necessary to have the correct subnet mask for the network and a default
gateway (router).
If you intend to use a DNS server, you will also need its IP address and the DNS domain.
Server name (setting not mandatory)
In order to assign symbolic names to the computers, the relevant nodes to be addressed
within the network can be entered so that their names can be resolved:
Server name:
192.168.0.20
192.168.0.21
With these settings computers R2345 and R2346 can be addressed by means of their
symbolic names.
