I think what that screenshot is saying is that after you deploy MAP, then if you stop using it the IPv6 addresses don't need to change. I would assume you're not saying that you can take your IPv6 addresses as you find them and interpret them as MAP End-user prefixes.

Hi Tom,

Good question.

The End-user IPv6 prefix can be constructed using whatever techniques
independent of MAP etc. in any deployment requiring IPv4 address sharing.

What is interesting is that the MAP enabled CPE could parse certain bits
of that IPv6 prefix to mean something for MAP. That's it. Attached is a
screenshot to illustrate this very point.

In what sense do you mean that? The end-user IPv6 prefix certainly ties
IPv4 and IPv6 together, hence the interest in the Light-Weight IPv4 over
IPv6 alternative.

UmmmÅ  you mean the IPv6 and IPv4 inter-dependency when you say IP

If so, the answer is Yes. v6 addressing doesn't need to change to
accommodate this IPv4 A+P encoding.
