You know, if I were the architect, I'd be tempted to suggest a carrier-grade NAT solution just to see the customer's reaction. But that's probably not the best idea for this scenario.

I see your point, Rex, but I still think stateful NAT64 is the most suitable option for this specific requirement.

Ha! I bet the architect is wishing they had a crystal ball to see the future network needs. Better play it safe and go with the classic stateful NAT64.

Hmm, I think option A is the way to go. Stateful NAT64 seems like the most straightforward solution to connect the IPv6 hosts with the legacy IPv4 devices.
