What you said is correct only if hosts use IPv6 addresses that are not "IPv4 compatible". But transition with hosts that don't have IPv4 compatible addresses is quite messy.
Yakov; If you have an IPv6 capable host, why use "IPv4 compatible" addresses? Why not use an algorithmic translation that includes a provider prefix? It would seem to me that any IPv6 host should have the capability to algorithmically translate its IPv4 address, preferably dynamically. --Kent
