Thanks for your information.
I just subscribed :)

Yes.
But actual key point is that the translator interface can separate DNS Proxy from NAT-PT.

If a translator has NAPT-PT rule for IPv6 to IPv4 translation, the translator interface is not required.
In this case, a translator maps a lot of IPv6 source addresses to one IPv4 source address,
so DNS Proxy doesn't need to care an IPv4 source address.
