You miss the point. It is unrelated to responding to broadcast pings -- thats perfectly fine behavior. The problem is one of sending to the broadcast address by accident, because that allows you to reply to a packet who's source address is the broadcast address without realizing that you might do so. .pm Mike Raffety says:
At my REQUEST, Wellfleet changed the behavior of their router software so that it WOULD respond to broadcast pings (ones aimed at networks on which the router has an interface directly attached, that is). In general, routers do NOT know that a particular packet is directed to a broadcast address; that's up to the end router to deal with, setting a broadcast MAC address in the final hop. I frequently use "broadcast pings" to see what's on a network.
