It's useful to note that the implementation of any A+P based scheme on an
end host has practical challenges, irrespective of what drafts say (just
think of two such host on the same LAN - something that is not allowed)
If it helps think of any of 4rd, 4V6, dIVI-PD, as having the same
applicability, but practically being most suitable for a CE alongside NAPT44
(which all rely on to provide address sharing)
