Which is actually used by some routing hardware. Ascend Pipelines have a
mode ("Proxy Mode=Always") in which the router answers any ARP request for
off-net IPs with its own MAC address. The idea then is to configure all
your machines to assume the entire Internet is on your local subnet and
the router will pick up the packets destined for the outside world
automatically. Kinda silly really but it does happen.
