Use Static IP Address Settings Suggested for the GPIB-ENET/100
The best way to assign your GPIB-ENET/100 a static IP address is to work with your network administrator, as network problems can occur if improper settings are selected. However, if you are using an unmanaged network or a crossover cable, the IP address settings suggested by the Add GPIB-ENET/100 Wizard may be useful.
When you use the Suggest Values button in the Add GPIB-ENET/100 Wizard to get suggested static IP address settings, your computer network settings are used as a basis for the suggestions. If the GPIB-ENET/100 will use the same subnet as your computer, you most likely can reuse the Gateway, DNS Server, and Subnet Mask settings. The IP Address field, however, must be changed. For a more detailed description of these fields, refer to Static IP Parameters.
IP Address Selection
The initially suggested static IP address is the subnet address of the network your computer is using and cannot be used for your GPIB-ENET/100. This address was generated by combining your computer's IP address and subnet mask values, and is separated into four numbers, or octets.
To generate a valid IP address inside the subnet range, use the suggested IP address and the subnet mask from the Add GPIB-ENET/100 Wizard. If an octet in the subnet mask is 255, you should not change the corresponding octet in the suggested IP address. If the subnet mask octet is 0, you can give the corresponding octet in the suggested IP address a value in the range 1254. For other subnet mask octet values, consult your network administrator or an IP address reference to determine a range of values that can be used. When you have determined a value for each octet in the IP address, make sure the entire address is unique on your network.
Multihomed Computers
Computers with more than one network interface are known as multihomed. The suggested IP address values are generated from the first active network interface discovered, and not necessarily the interface by which the GPIB-ENET/100 is connected to your computer. Be sure the settings are correct for the GPIB-ENET/100 network.
Assigning Static IP Addresses on a DHCP Network
Assigning a static IP address on a dynamically configured network is not recommended. If you are using a static IP address anyway, be sure to work with your network administrator to assign an address that the DHCP server will not also assign.
