IP Configuration
Default
Static
Options
Static, DHCP
Description
This field determines how the NPort’s IP address will be assigned.
Static: IP address, netmask, and gateway are user-defined.
DHCP: IP address, netmask, gateway, DNS, and time server are assigned by the DHCP
server.
IP Address
Default
192.168.126.254
Options
IP address (e.g., “192.168.1.1”)
Description
This field is for the IP address that will be assigned to your NPort device server. An IP
address is a number assigned to a network device (such as a computer) as a permanent
address on the network. Computers use the IP address to identify and talk to each other
over the network. Choose a proper IP address that is unique and valid in your network
environment. If your device server will be assigned a dynamic IP address, set the
IP
configuration
parameter appropriately.
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.
