just my personal humble understanding: basically MAP or 4rd, as it is named, is designed for residual deployment, i.e., using not-yet-allocated or already-recalled ipv4 addresses for the ipv4 access of ipv6-enabled networks. its address mapping logic implies doing the ipv6 address planning as the first step, independent of ipv4.
for the transition of existing ipv4 network without renumbering (or only renumbering to ipv4-translatable ipv6 addresses), MAP is also applicable but the operator should pay much attention to the addressing issue. in such a case, RFC6052/RFC6145 suite is a little better recommended. - maoke 2012/2/8 Cameron Byrne <[email protected]> > Are the map and 4rd solutions deployable for existing networks that do not > have reserves of ipv4 ?
