Subnet Mask (Modifiable)
Displays the subnet mask for the module. A subnet mask “masks out” the
network bits of the IP address by setting the bits in the mask to 1 when the
network treats the corresponding bits in the IP address as part of the
network or subnetwork address, or to 0 if the corresponding bit identifies
the host. When an IP address is entered in the IP Address field, the subnet
mask field automatically enters the default subnet mask for the IP address.
For details about how to change the subnet mask from its default value,
refer to
Section 5.15.2 .
