Confirm your changes and exit the NI Ethernet Device Configuration
utility.
The GPIB-ENET/100 automatically reboots with the new configuration in
effect.
Static IP Parameters
If DHCP is not available, you must provide the GPIB-ENET/100 with
several important network parameters.
•
IP address
—The unique, computer-readable address of a device on
your network. An IP address typically is represented as four decimal
numbers separated by periods (for example,
130.164.54.215
).
Refer to the
section.
•
Subnet mask
—A code that helps the network device determine
whether another device is on the same network or a different network.
•
Gateway IP
—The IP address of a device that acts as a gateway, which
is a connection between two networks. If your network does not have
a gateway, set this parameter to
0.0.0.0
.
•
DNS Server
—The IP address of a network device that stores
hostnames and translates them into IP addresses. If your network does
not have a DNS server, set this parameter to
0.0.0.0
.
Choosing a Static IP Address
For a Network Administered by a Network Administrator
If you are adding the GPIB-ENET/100 to an existing Ethernet network, you
must choose IP addresses carefully. Contact your network administrator to
obtain an appropriate static IP address for your GPIB-ENET/100. Also
have the network administrator assign the proper subnet mask, gateway,
and DNS server addresses.
For a Network without a Network Administrator
If you are assembling your own small Ethernet network, you can choose
your own IP addresses. The format of the IP addresses is determined by
the subnet mask. You should use the same subnet mask as the computer
you are using with your GPIB-ENET/100. If your subnet mask is
255.255.255.0
, the first three numbers in every IP address on the
network must be the same. If your subnet mask is
255.255.0.0
, only the
first two numbers in the IP addresses on the network must match.
