Thanks, will read it.

Jim, I fully agree. Yet, unfortunately, as long as "with IPv6" does mean supporting IPv4+IPv6 together, we will get rather more complicated applications because these now need to support IPv4 with NAT *and* IPv6 without it.

Up to now, whenever I see an IPv6 rollout planned in a NATed IPv4 environment, this usually means adding IPv6 with a stateful firewall to the existing IPv4 with NAT (which will be kept).

We'll see how long this "standard solution" will persist in the future...

Best regards
