An IP address is recognised as being local if there is an interface with
that IP address, which has a route through it.  This is why you need
both of the following (presuming `hostname` can be resolved to your own
IP address):

	ifconfig dummy `hostname`
	route add -host `hostname` dummy

No packets actually get sent to the interface.  You can actually compile
statistic into the dummy driver (look for "#undef DUMMY_STATS" in dummy.c)
and see that this is so.
