er, again, not true. the space was originally, net/host - the mantra was "bridge where
you can, route when you must" - there were expected to be a few networks with millions
of hosts within each broadcast domain. (anyone else remember the ARP storms of the
1970s/1980s?)
routing came into its own later, along with classful addressing.
