IP configuration
Method Function Definition
Static User defined IP address, Netmask, Gateway
DHCP DHCP Server assigned IP address, Netmask, Gateway, DNS, and Time Server
DHCP/BOOTP DHCP Server assigned IP address, Netmask, Gateway, DNS, and Time Server, or
Server assigned IP address (if the DHCP Server does not respond)
BOOTP BOOTP Server assigns IP address
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 that 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 5100A 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 5100A, a connection is established directly from the NPort 5100A.
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 5100A
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
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 un
available, the firmware will use the default IP address (192.168.127.254),
etmask, 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 then 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
