The above are ARP broadcast packets.  ARP stands for Address Resolution
Protocol.

It is a bit strange to see these in your network since ARP broadcast packets
aren't supposed to survive past the subnet they are transmitted on.  The
purpose of the ARP request is to get the MAC address of a given IP address.
 Taking one line of your output above...
...
These packets are coming into your network. They are 42 bytes long. You'd have to have a whole heck of a lot of these to drive up your network usage.
 In any case, they are inbound and not associated with any requests from
your side so it is unlikely that the ISP is counting these as your traffic.





This is a clear indication of packet 'flooding' by your ISP. If you watch a dump long enough you will probably see all kinds of traffic.

Not so, those are broadcast packets. If you were correct, he'd be seeing replies too.
