In the first place, you replace the IPv4 --> IPv4 mapping with
{IPv6, IPv4} --> IPv4 mapping. See Section 5.6 of RFC 6333.Beyond that, the text I gave refers to a single mapping in the address map table. For different external IPv4 external addresses, you would be looking at different mapping instances.

Ok so if I understand correctly, you replace the IPv4 --> IPv4 address mapping with the IPv6 --> IPv4 address mapping in the case of DS-Lite. If that's right, then I don't see how it could work. There is not necessarily such an IPv6 --> IPv4 address mapping. The internal 192.0.0.0/29 <http://192.0.0.0/29> addresses could be mapped to different external IPv4 addresses. Or maybe I misunderstood your proposal... Simon
