Re: This is not rocket science... cable is a sheared link and they may be counting at the node or some other place that counts ARP traffic and attempts to send data to your modem. Also counts overhead as well.

But if it's a sheared link then the cable company shouldn't be billing for traffic at all. If they measure traffic sent on a sheared link, they have an even more fundamental problem with their system.
