NPort 5600 Series User’s Manual Web Console Configuration
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 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 will use the
subnet mask to check if 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, a connection is established
directly from the NPort. 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 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.
IP Configuration
Setting Factory Default Necessity
Static
DHCP
DHCP/BOOTP
BOOTP
Static Required
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.
DNS server 1 / DNS server 2
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.)
None Optional
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 the computer uses the response to connect
to the web server. DNS is the way that Internet domain names are identified and translated into IP
addresses. A domain name is an alphanumeric name, such as moxa.com, that it is usually easier to
remember. A DNS server is a host that translates this kind of text-based domain name into the
numeric IP address used to establish a TCP/IP connection.
In order to use NPort’s DNS feature, you need to configure the DNS server. Doing so allows
NPort to use a host’s domain name to access the host. NPort provides DNS server 1 and DNS
