That depends. If Amazon sees absolutely no ill effects from v6 users reaching it via v4, then they obviously have little technical incentive to migrate. OTOH, if that is true, then all the whining about how "evil" NAT-PT is is obviously bunk. We can't have it both ways, folks: either NAT-PT breaks things and people would move to native v6 to get away from it, or NAT-PT doesn't break things and there's no reason not to use it.
The IPv4 Internet has been awash with dodgy NATs that negatively affect functionality ever since NAT arrived on the scene. What has happened? Well, application protocols have evolved to accommodate NAT weirdness (e.g., SIP NAT discovery), and NATs have undergone incremental improvements, and almost no end-users care about NATs. As long as they can use the Google, BitTorrent and Skype, most moms and dads neither know nor care about any technical impediments NATs erect between them and their enjoyment of the Internet. There's no rational reason to believe that NAT-PT would be any different. If NAT-PT breaks stuff, it'll get improved. It'll keep getting better until we don't need it anymore (or forever, whichever comes first) - mark -- Mark Newton Email: newton@internode.com.au (W) Network Engineer Email: newton@atdot.dotat.org (H) Internode Systems Pty Ltd Desk: +61-8-82282999 "Network Man" - Anagram of "Mark Newton" Mobile: +61-416-202-223
