0xFFFFFF00 or 255.255.255.0, using the lower 8 bits for the host part of the IP
address. This allows up to 255 devices on the local subnetwork.
This default mask is the example shown in the menu above.
If the user desires to have multiple subnetworks with up to 32 devices on each the
subnetwork mask could define 5 “host” bits or 255.255.255.224. With this setting, the
decimal value 224 configures the lower 8 bits of the address, with the upper 3 of these
bits addressing up to 8 subnetworks, and the lowest 5 bits forming the part of the
address for the 32 local devices.
If you wish to specify a subnetwork mask, enter Y at the menu prompt and then enter
your values for the mask.
Enter N to use the default subnetwork mask of 255.255.255.0.
