IP_NetMask

This parameter gives the appropriate subnet mask for use on a particular network. This value must be provided by the network administrator. If there is only one active board using TCP/IP, the parameter takes a subnet mask as its only value:

IP_NetMask 255.255.255.0

The subnet mask is specified in standard dotted-decimal notation, one decimal number for each byte of the four-byte value. The underscore character ('_') in IP_NetMask” is required.

If the machine has multiple boards using TCP/IP, then an additional network name value is required to associate each mask assignment with its proper board:

IP_NetMask 255.255.255.0 EXEC_NET

IP_NetMask 255.255.255.128 SALES_NET

The network name value is used in conjunction with the “Bind” parameter to associate the correct subnet mask information with each board instance.
