this does not answer the op's question. and dual stack assumes that<br>
you can get as much ipv4 space as needed to number your enture network.<br>
this assumption is no longer safe, at least without significant expense.<br>
<br>
nat64/dns64 at the edge of a v6-only enterprise, or a not too large<br>
v6-only network is the expected solution to this scenario.<br>
<br>
and i suspect that mark tinka will be the best source of info on which<br>
boxes and versions; so i will avoid putting my foot in it. otoh, you<br>
might give somme clue as to how big a 6-only network you want to nat.<br>
