Rogers Canada using for internal address space

As of April 27th I have started to receive dhcp broadcast requests
originating from the network. Based on MAC addresses, it
seems that this is communication between the Rogers border/node
hardware (MAC assigned to Cisco) and my Motorola cable modem.

Is the DoD releasing this range to Rogers? Or has Rogers squatted on
this space due to exhaustion of their 10/8 use? We've seen other
vendors and ISP squat on previously unused ranges (the 1/8 or 5/8s).
Could they not wrap their internal cable modem to node chatter in
IPv6, instead of using assigned address space?
