Hosts should also accept AS BROADCASTS any packet that was sent to the link layer broadcast (and mulitcast???) address regardless of what the IP address was. David Bridgham Well, now, I would not put it quite that way. To be an acceptable IP broadcast datagram, it must have a recogizable IP broadcast address in its destination field. The problem we need to solve is the havoc (broadcast storms, etc) created by datagrams which arrive by local network broadcast but do not have a recognizable IP broadcast address. The discussions in the IETF Host Requirements Working Group have concluded that the best thing to do with such datagrams is SILENTLY IGNORE THEM. Bob Braden
