The all-zeros address really means ``this host'' or ``I don't know'', but for our purposes treating it as a broadcast address gives useful enough behavior. The code which no longer exists of which you are probably thinking is the kluge in ip_input() which would accept such packets as broadcasts even when that address was not configured as an interface's broadcast address. > Also, i can't get rid of this bogus cloned route.
