Constant ARP requests from Cox WAN

Anyone else noticed the near constant ARP requests occurring over your Cox modem WAN link? All this needless traffic just ARPing out to every cable modem from all over is chewing up cycles.  Maybe it's just the AZ market, but all the connections I manage have the same behavior.  There's one exception.  The G1gablast fiber network does not have the same arp flooding observed.

I would only expect to see the ARP for a site's assigned IP once in a blue moon, but instead here's 5 seconds of noise:
