I think you miss the point. With arp poisoning, I can see all traffic on a given switch, and I do not even need an IP address. Apr is at Layer 2. IP does not come in until Layer 3. The fix is switches that limit arp floods. Of course, then you go the the AP, and most of them can not limit arp, so your netcut guy on wireless still can see everything in that AP. Lee
