6-4
IP Configuration
Default
Static
Options
Static, DHCP, DHCP/BOOTP, BOOTP
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
DHCP server.
DHCP/BOOTP: IP address, netmask, gateway, DNS, and time server are
assigned by DHCP server. IP address is assigned by BOOTP server if DHCP
server does not respond.
BOOTP: IP address is assigned by BOOTP 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. 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.
