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.
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
.
