For either subnet mask, numbers between 1 and 254 are valid choices for
the last number of the IP address. Numbers between 0 and 255 are valid for
the third number of the IP address, but this number must be the same as
other devices on your network if your subnet mask is
255.255.255.0
.
If you are setting up your own network, you probably do not have a gateway
or DNS server, so you should set these values to
0.0.0.0
.
Verifying the Hostname
The NI Ethernet Device Configuration utility automatically verifies that the
hostname for each DHCP-enabled device matches the DNS entry for the
assigned IP address. This verification process automatically occurs when
you either run the utility or refresh the list of devices. The utility alerts you
if it detects a problem with the network settings.
To correct the problem with the hostname, complete the following steps:
1. Locate the device that has a problem. This is indicated by an
exclamation point (
! ) on the device icon.
2. View the properties for the device. The utility displays four options for
resolving the verification error. Select the one that best fits your
situation.
• Change the device’s hostname to match the DNS entry —Use
this option if you want to accept the hostname assigned by the
DHCP server, or if you cannot contact the network administrator
to change the DNS entry.
• Use static network parameters instead of DHCP —Use this
option if you cannot use the hostname assigned by the DHCP
server. Contact your network administrator to obtain a valid IP
address, subnet, and gateway. This option disables DHCP on the
device.
• Edit the current hostname —Use this option to change the
hostname to a name other than either the configured hostname or
the name assigned by the DHCP server. Contact your network
administrator to obtain a valid name.
• Keep the existing hostname —Use this option if you want to keep
the previously assigned hostname. If you select this option,
contact your network administrator to change the DNS entry.
3. Confirm the network parameter settings. The device reboots with the
new settings in effect.
