The ARP stuff that doesn't belong may be for backwards compatibility with old IP ranges/designs...
Anyone remember when Shaw or Videon was transitioning to a new IP range, if you manually configured your machine for any static IP on the old range it would work? Some people did that for lower latency to the UofM/MTS since the old network connected in Wpg but the new network went to their IXes in Calgary/Toronto/etc. before geting on to the internet.

Hmm, I'm not sure I follow... been up too long! Not sure why Shaw's routers would relay bc's across subnets sourced from random nitwit's broken client/router? This is type "Boot Reply (2)" which should be coming from the DHCP server back to the client?
I'd be interested to see the packet.
At least with ARPs you see all sorts of subnet leakage. Do a "tcpdump arp" some day and watch for stuff that doesn't belong, most of it comes from Shaw routers.
