As per my original post to this thread, that would remove all traffic from Akamai on-net nodes, Google's GGC nodes, Netflix's on-net Open Connect nodes, and many others.

If you are a broadband network in many countries, that is well over half the traffic going down your customer's pipes.

I think most people would alter their definition to count that traffic.

I don't think the type of packet (DNS, HTTP, SMTP, etc. or even TCP, IP, ICMP) should matter.
