Of course it gets to use ARP, nothing prevents this. If I know that IP X has my configuration information, I have every right to send X a packet from zero-net to ask for that information before I have any IP addresses attached to the interface. This is nothing wrong nor strange about this and we've supported it for years. Also, when one specifies a specific device in an output address and we cannot find the IP part of the address in the routing tables, we still procure a valid route for the requester. Besides normal IP addresses, multicast tools use these facilities. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
