Description of Problem:
When configuration a network interface manually, you must enter in both an IP
address and a netmask. It might be convenient if the system pre-filled in the
netmask field with the default netmask based on the IP address as was done in
previous releases. (i.e., 255.0.0.0 for class A (1.x.x.x - 127.x.x.x),
255.255.0.0 for class B (128.x.x.x - 191.x.x.x) and 255.255.255.0 for class C
(192.x.x.x - 223.x.x.x))
I'm not sure why I'm suggesting this, actually -- I don't even use default
netmasks for my own network. Perhaps I'm just so accustommed to seeing that
that it feels wrong if it isn't there.
Related to bug 67124.
With the advent of CIDR, this isn't overly relevant anymore
