iPhone a DDoS Device?

Bad iPhone bad bad…

The misbehaving iPhones flood the access points with up to 18,000 address requests per second, nearly 10Mbps of bandwidth, and monopolizing the AP’s airtime.

The requests are for what is, at least for Duke’s network, an invalid router address. Devices use the Address Resolution Protocol (ARP) to request the MAC address of the destination node, for which it already has the IP address. When it doesn’t get an answer, the iPhone just keeps asking.
