7-5
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 of the network hosts at one
geographic location, in one building, or on the same local area network (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.
