OK, so the NAT is taking place in the router you got from Comcast, not
in Carrier Grade NAT in Comcast's network. A fine distinction but an
important one. The external address of your router is (a) globally
unique, and (b) not shared with any other customer.

Who told you that?
I offer you as a counterexample (all? maybe just every one I've
owned?) the Airports from Apple. Default LAN address is 10.0.1.1.
