IP address
Setting Factory Default Necessity
E.g., 192.168.1.1 (IP
addresses in 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), which works as a permanent
address on the network. Computers use IP addresses 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 the network hosts at one geographic location, such as all the hosts in a building
or on the same local area network. When a packet is sent out over the network, the NPort IA5150A/IA5250A
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 IA5150A/IA5250A, a connection
is established directly from the NPort IA5150A/IA5250A. Otherwise, the connection will be established through
the given default gateway.
Gateway
Setting Factory Default Necessity
E.g., 192.168.1.1
None
Optional
A network gateway acts as an entrance to another network. Usually, the computers that control the traffic
within the network or at the local Internet service provider are gateway nodes. The NPort IA5150A/IA5250A
needs to know the IP address of the default gateway computer in order to communicate with hosts outside the
local network environment. To obtain correct gateway IP address information, consult your network
administrator.
IP configuration
Setting Factory Default Necessity
Static, DHCP,
DHCP/BOOTP, BOOTP
Static Required
ATTENTION
In Dynamic IP environments,
the firmware will retry every 30 seconds, up to three times, until network
settings are assigned by the DHCP or BOOTP server. The
timeout for each try increases from one
second, to
three
seconds, then to give seconds.
If the DHCP/BOOTP
server is unavailable, the firmware will use the default IP address (192.168.127.254),
m
etmask, and gateway as IP settings.
DNS server 1/DNS server 2
Setting Factory Default Necessity
E.g., 192.168.1.1
(IP addresses in the
form of x.x.x.0 and
x.x.x.255 are invalid.)
None Optional
When a user wishes to visit a website, the computer will request 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
how Internet domain names are identified and translated into IP addresses. A domain name is an alphanumeric
name, such as moxa.com, which makes it easier for people to remember. A DNS server is a host that translates
this kind of text-based domain name into numeric IP address to be used for establishing a TCP/IP connection.
