A few more RFCs, a few more IP over IP bandaid, a few more extensions, and we will get there. By God IPv6 is a stain in the history of computer science.

IPv6 should have really just worked like NAT/IP over IP on IPv4 hardware and fast path on IPv6 hardware. But instead we got a monster that keeps growing with things like NAT64, 4over6, DS-Lite, MAP-E, and now BGP stopgaps and a growing

This literally exists. There's no need for it to be part of the original specification because it's a completely separate concept.

There's nothing wrong with ipv6 other than the general human desire to not change things that "work" and for people who are currently powerful because they own a bunch of ipv4 to resist changes.

If your solution is that “if everyone just used IPv6 we wouldn’t have this problem” then it’s not a solution. Standards like USB, Wi-Fi, HDMI, DP, etc. are so successful because they are by out-of-the-box backwards compatible with their predecessors.

The unfortunate reality is that technology exists to serve us. If humans don't want to use it, it means that your technology is wrong. End of story. It doesn't matter if you (or any of us) think it's elegant and beautifully designed.

By that token, IPv6 never had to exist at all then, but we know that is completely missing the point.

IPv6 is a privacy nightmare without privacy extensions. It is designed with "a stupid desire to pretend we can boil the ocean".

Close to 3 decades and we are barely scraping 50%: https://stats.labs.apnic.net/ipv6/

Running a IPv6-only network that doesn’t interact with IPv4 networks in any way is great and it works.

The actual gap is the mess of mixing/transitioning, and it wasnt planned properly in the last 30years

		Yeah, that is the whole point. It was never going to be a clean cut. "Works in my lab" isn't good enough for real world. The issue isn't that it wasn't planned properly, the issue is that the real world wasn't taken into consideration by people who either worked for the likes of Google who were aching for a globally unique identifier per device or just delusional about how much we can change in real world.

This isn't one of those. It's for ISPs who run a native IPv6 backbone and want to exchange and route IPv4 traffic without setting up IPv4 addressing.
