All hosts on the local network, including routers.

FreeBSD does not send it out on all interfaces, but only on the default 
interface. That seems like a good solution to me - in fact, this is how lwIP 
does it as well. Since the destination address doesn't match any of the 
network interfaces' addresses, it sends it out on the default interface.
