Choosing Network Settings
This appendix describes how to choose appropriate network settings.
Choosing an IP Address
The way you choose an IP address for your FP-20 xx may depend on
whether your network has a system administrator.
Choosing an IP Address with a Network Administrator
If you are adding the FP-20 xx to an existing Ethernet network, you must
choose IP addresses carefully. Consult with your network administrator to
obtain appropriate values:
• Ask the administrator to provide static IP addresses to your FP-20 xx
and to the computer running the National Instruments Time Service.
Time Service is installed along with the FieldPoint software and runs
automatically.
• Ask the network administrator to provide the proper subnet mask,
gateway, and DNS server addresses.
Choosing an IP Address without a Network Administrator
If you are assembling your own small Ethernet network, you can choose
your own IP address. The following guidelines may help you choose
appropriate values:
• IP Addresses are generally in the form of
w.x.y.z
where
w
,
x
, and
y
are numbers between 0 and 255 (inclusive) and
z
is between 1 and 254;
however, a
z
value of 1 is usually reserved for the IP address of a
gateway.
• Local networks (those that will not be connected to the Internet) should
have IP addresses assigned from the following ranges:
–
10.0.0.0
through
10.255.255.255
–
172.16.0.0
through
172.31.255.255
–
192.168.0.0
through
192.168.255.255
