In the article Comcast claims their average customer uses 2-3GB a month. I wonder if that includes all the ARP traffic that is sent to their system thanks to Comcast's network design. (Assuming it's the same elsewhere).
In 5 minutes, 150,285 bytes were received by my otherwise idle cablemodem. Multiply by 6, that's 901,710 bytes in an hour. Multiply by 24, that's 21,641,040 bytes in a day. Multiply by 30, that's 649,231,200 bytes in a month of JUST ARP TRAFFIC!
Hey Comcast, do you think it'd be worthwhile to reconfigure your network so I'm not getting 600+ MB of ARP requests for non-existent IPs a month?
