You probably heard this from me.  Our Guest LAN simulation does NOT use
the netmask value to direct or filter the IP frames sent over Guest LAN.
When I first learned that the netmask was available on the command that
is used to register an IP address, I thought it would be useful to display
the associated netmask.  I assumed it would be the "subnet mask" and the
QUERY LAN with DETAILS would help determine if somebody had configured a
bad
netmask.  In practice, the drivers seem to be sending the "network mask"
instead of the "subnet mask" so this display is not as helpful as I would
have hoped.

The netmask might vanish from those CP responses at some point in the
future.

Regards,
Dennis
