IP address

Setting

Factory Default

Necessity

E.g., 192.168.1.1
(IP addresses of the form x.x.x.0 and
x.x.x.255 are invalid.)

192.168.127.254 Required

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 which is unique and valid in your network environment.

Netmask

Setting

Factory Default

Necessity

E.g., 255.255.255.0

255.255.255.0

Required

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 5110 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 NPort 5110, a
connection is established directly from the NPort 5110. Otherwise, the connection is established
through the given default gateway.

Gateway

Setting

Factory Default

Necessity

E.g., 192.168.1.1

None

Optional

A gateway is a network gateway 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. NPort 5110 needs to know the IP address of the default gateway computer in order
to communicate with the hosts outside the local network environment. For correct gateway IP
address information, consult the network administrator.

ATTENTION

In Dynamic IP environments, the firmware will retry 3 times every 30 seconds until network
settings are assigned by the DHCP or BOOTP server. The Timeout for each try increases from 1
second, to 3 seconds, to 5 seconds.If the DHCP/BOOTP Server is unavailable, the firmware will
use the default IP address (192.168.127.254), Netmask, and Gateway for IP settings.

When the user wants to visit a particular website, the computer asks a Domain Name System
(DNS) server for the website’s correct IP address, and then the computer uses the response to
