Sure... For DS, I could send IPv6 native and IPv4 via NAT. I suspect this actually the most common home setup at this point. It's certainly the way mine looks. I have noticed that IPv4 "feels" slow on my t-mobile usa connected devices. This is only a problem when interacting with legacy players on the network, eg: financials, opensrs, airlines. I suspect this is a 64 CGN tax. Waiting to see my other devices/sims see IPv6 on them via VZ and AT&T.
If your IPv4 is public, you should not "feel slow". Of course, if your IPv4 is private, then yes, some NAT44 may happen somewhere along the path.
Sure, but your v4 is likely to have issues regardless and face this penalty/tax.
But that would be a function of NAT44 if you're on private IPv4, and have nothing to do with the NAT64. In our deployment, we do not offer customers private IPv4 addresses. I suppose we can afford to do this because a) we still have lots of public IPv4, b) we are not a mobile carrier. So any of our customers with IPv4 will never hit the NAT64 gateway. When we do run out of public IPv4 addresses (and cannot get anymore from AFRINIC), all new customers will be assigned IPv6 addresses. These will hit a NAT64 gateway if they want to talk to legacy resources on the Internet. Mark.
