Hi Joe - When I used to have Adelphia (I've since given up on them and gone to Verizon DSL) my traceroutes would lead out to a 10.x.x.x address. In other words, my address was on the 10.x space, as was my default router. From there it was blackholed as it traversed their network, and would I would get globally routed addresses at their ingress/egress point. I never saw any 192.168.x.x addresses.
