I cannot see how this is even possible. If I use private space internally to the CGN, then the available external space 
is the same and the internal customers are the same and I can do the same over sub ratio under both circumstance. Tell 
me how the math is different.

See response to answer 1

Interesting, but I’m not sure how any over-loaded NAT translation would look different from the external system. Since 
you cannot explain it, it’s hard to discuss it.

The math would be the same as a CGN, so I do not see how this is any less or more useful. It does, however, require CPE 
capability that appears lacking and NAT444 does not.
