If my impression is correct, then my feeling is that something else is required. I am somewhat skeptical that shim6 will be implemented in any near term timeframe and it will take a very long time for existing v6 stacks to be upgraded to support shim6. What I suspect will be required is real _site_ multihoming. Something that will take existing v6 customer sites and allow them to be multi-homed without modification to each and every v6 stack within the site.
if all you've got is a hammer, every problem looks like a nail. so, the above problem statement looked like a dns issue to me, and to some other folks, and thus was born A6. had ietf killed AAAA back when there were effectively zero ipv6 hosts on the 'net, and paid the apparently-high A6 complexity penalty, we'd be talking about something else by now. as it is, the shim6 complexity penalty is even higher, and i don't think we'll ever get to stop talking about this problem. -- Paul Vixie
