How many instances of 10/8 did they say they were running?  I was behind
a NAT when I had Comcast service. I am behind a NAT currently with my
AT&T service.

Note that the NAT was done on the "cable modem" in both cases and not
further in to their network.  That said, from my reading of some
industry large scale NAT devices (the A10 AX series is one which I am
familiar with), they do things such as full cone NAT so it will still
work with many applications that might break with conventional overload
dynamic NAT.
