OK, I'll bite.

Let's assume what many people now seem to concede, which is that a large
part of the Internet is going to continue to be IPv4-only. So, what's the
functional difference between:

- A host which has an IPv6 only address, which it cannot use (without
"borrowing" a global IPv4 address) to comunicate directly with IPv4-only
hosts out on the global Internet.

- A host which has an IPv4 local-only address, which it cannot use
(without "borrowing" a global IPv4 address) to comunicate directly with
other IPv4 hosts out on the global Internet.

that the former can communicate with all other nodes with globally reachable IPv6 addresses, without having to borrow a global IPv4 address to do so?


I'll leave it as an exercise for the reader to figure out whether this is a *significant* functional difference - but it *is* a functional difference, and that was what you asked for, Noel....
