WL#2686: CIDR NETMASK in host

Currently you can specify a NETMASK in the host portion of the connection info but 
it only dictates which class of the address to apply (8,16,24,32 bits).  You 
cannot apply 28 bits of the address so this does not work as normally expected:
192.168.1.96/255.255.255.240.

This came from a support customer's request and I agree with them although it's 
not an all too important task.
