Alan - this is from man ifconfig on HP-UX 10.20:

   Supernets
     A supernet is a collection of smaller networks.  Supernetting is a
     technique of using the netmask to aggregate a collection of smaller
     networks into a supernet. This technique is particularly useful for
     class C networks.  A Class C network can only have 254 hosts.  This
     can be too restrictive for some companies.  For these companies, a
     netmask that only contains a portion of the network part can be
     applied to the hosts in these class C networks to form a supernet.
     This supernet netmask should be applied to those interfaces that
     connect to the supernet using the ifconfig command.  For example, a
     host can configure its interface to connect to a class C supernet,
     192.6, by configuring an IP address of 192.6.1.1 and a netmask of
     255.255.0.0 to its interface.

And this is the example on HP-UX 10.20:

# ifconfig lan0 191.1.1.1 netmask 255.255.255.224
# ifconfig lan0
lan0: flags=862<BROADCAST,NOTRAILERS,RUNNING,MULTICAST>
        inet 191.1.1.1 netmask ffffffe0 broadcast 191.1.1.31
# ifconfig lan0 192.1.1.1 netmask 255.255.255.224
ifconfig: ioctl (SIOCSIFADDR): Can't assign requested address
# ifconfig lan0 192.1.1.1
# ifconfig lan0
lan0: flags=862<BROADCAST,NOTRAILERS,RUNNING,MULTICAST>
        inet 192.1.1.1 netmask ffffff00 broadcast 192.1.1.255

I can only say - 'This is HP :-)'. Their ideas are sometimes strange for
me. :-).
