IP Address Allocation
The IP addresses are allocated so that they are unique for each node in the network (or be-
tween two or more networks). If two or more nodes are allocated the same IP address, the
remote nodes with the same IP address will also malfunction.
IP (Internet Protocol) is a communications protocol that conforms to international standards.
Therefore, to connect to the Internet, always obtain IP addresses that have been allocated by
a public organization (i.e., the NIC in the country of use, such as the JPNIC in Japan). Using
IP addresses that are not recognized by the NIC (JPNIC) to connect to the Internet could
have unforeseen social consequences, such as causing the networks of another organiza-
tions to malfunction unexpectedly.
Local IP Address
The local IP address indicates the IP address of the Ethernet Unit that is used to set the set-
tings.
The following IP address settings are not possible.
Subnet Mask
When more than one node is connected to the network, network operation and management
can be difficult. Therefore, for convenience, configure the system by dividing a single network
into multiple sub-networks. The system operates internally as multiple networks, but exter-
nally appears as a single network.
To operate a system in this way, divide the host ID field of the IP address into a subnet ID
field and a host ID field.
The subnet ID field is identified by the information in the subnet mask. The subnet mask is a
bit mask in which the net ID and subnet ID fields are 1 and the host ID field is 0.
The subnet mask must have a value that is common to all nodes on the same sub-network.
Setting the subnet mask is not required if sub-networks are not used. The system recognizes
subnet masks without a subnet ID field (i.e., subnet masks with net ID and host ID fields
only).
Net ID with all bits set to 0 or 1.
Host ID with all bits set to 0 or 1.
Subnet ID with all bits set to 1.
IP addresses that begin with 127 (7F Hex) (e.g., 127.35.21.16).
Example: 11111111 11111111 11111111 00000000 → FFFFFF00
