Netmask
Default
255.255.255.0
Options
Netmask setting (e.g., “255.255.0.0”)
Description
This field is for the subnet mask. A subnet mask represents all the network hosts at one
geographic location, in one building, or on the same LAN. When a packet is sent out over
the network, the NPort device server will use the subnet mask to check whether the
desired TCP/IP host specified in the packet is on the local network segment. If the address
is on the same network segment as the device server, a connection is established directly
from the device server. Otherwise, the connection is established through the gateway as
specified in the
Gateway
parameter.
Gateway
Default
Options
IP address (e.g., “192.168.1.1”)
Description
This field is for the IP address of the gateway, if applicable. A gateway is a network
computer that acts as an entrance to another network. Usually, the computers that control
traffic within the network or at the local Internet service provider are gateway nodes. The
NPort device server needs to know the IP address of the default gateway computer in order
to communicate with the hosts outside the local network environment. Consult your
network administrator if you do not know how to set this parameter.
