6. If the network that this node is on contains ANY internetwork
gateway (either full or half) press the
[Neighbor Gateways] key and
proceed to the section in this chapter called “Configure Neighbor
Gateways.”
7. If the network that this node is on contains NO internetwork
gateways or if you have already configured gateways for this system,
press the
[Config Directry] key and proceed to the section in this
chapter called “Configure X.25 Virtual Circuits.”

IP address The IP address is an address of a node on a network. An
IP address has two parts: a network portion and a node
portion. The network portion must be the same for all
nodes on an X.25 network; the node portion must be
unique for all nodes on an X.25 network.
HP assigns the network portion (initial nine digits) of
IP addresses from ARPA Class C, though your
addresses may also be of Classes A or B. The complete
formats are:
Class A: nnn.xxx.xxx.xxx
Class B: nnn.nnn.xxx.xxx
Class C: nnn.nnn.nnn.xxx
Where: nnn
= the network portion of the IP address
and
xxx
= the node portion of the IP address
Note: A space separates the network and node
portions of the IP address.
For Class C, the node portion of the IP address must be
between 000 and 255.
If you are adding your NS 3000/iX node to an existing
NS 3000/V network, the network portion of each node's
IP address should be the same. You will have to find out
what this is, and use it in the network portion of the IP
address of your NS 3000/iX node. Also, you will need to
know the node portions of the IP addresses of each of
the nodes (usually they will be numbered sequentially,
such as 001, 002, and so on), so that you can specify a
unique node portion for the IP address of your node. If
you have a network map, it should provide a record of
