A number of IETF documents(*) state that there are some service providers
that place a NAT box in front of their entire network, so all their
customers get private addresses rather than public address.
It is often stated that these are primarily cable-based providers.

I am trying to get a handle on how common this practice is.
No one that I have asked seems to know any provider that does this,
and a search of a few FAQs plus about an hour of Googling hasn't
turned up anything definite (but maybe I am using the wrong keywords ...).

We nat a portion of our residentail users -- not all of our network. As I
recall our current nat pools are comprised of a /21
