Re: [v6ops] I-D Action: draft-ietf-v6ops-nat64-srv-00.txt

Chair hat off.

The biggest concern or question that I have in this is that it appears that networks now have an *expectation* that there is a NAT64 and a DNS64 somewhere in the network, which to my knowledge is only a reasonable expectation during the transition period. To put that in context, I at one time used an HE tunnel to provide IPv6 service in my home, and then my upstream (which was first Cisco and later Cox) provided that service. So I *could* have had a NAT64 in my home, and then the service moved to whoever was upstream of me. Over time, One could imagine the service moving again. If I were maintaining my DNS service, they would have to track that changing landscape, which I could imagine becoming a headache.

So the intent of the draft makes sense to me. I find myself wondering about the operational implications. Maybe you can fill me in?

The fact that there is a highway to hell and a stairway to heaven is an interesting comment on projected traffic volume...
