So, these intermediate steps are just cooking the final dish.
Peace. ;)
They would need to be forced to move by customers, probably through an ISP being IPv6 only. And that probably won't ever happen as the customers of those ISPs would drop them for one that does support IPv4 because they expect access to the same big businesses mentioned earlier.
I think the whole thing has lots of inertia to not move to IPv6 and there's no incentive to force it.
Shame on you Turk Telekom and Turkcell. Still don’t support IPv6.
That’s the only thing about IPv6 that I’ve heard of that I think is a reasonable argument regarding a degradation in privacy.
With that said, NAT was a fix for issues that weren’t about privacy, and NAT itself was not designed to give you privacy. It used to be that IPv4 connections were always direct in the same way IPv6 connections were designed to be direct.
In that regard you could make the argument that IPv6 is a regression, but that regression is effectively answering for an architectural shortcoming in IPv4 that we’ve tried hard to fix but that can only go so far.
Edit to add: NAT also doesn’t protect anyone’s privacy anymore than their ISP is willing to protect it anyway, for what it’s worth.
