If UTF-8 represents the triumph of a design prioritizing backwards compatibility with an existing standard (ASCII) to facilitate a transition, then IPv6 is the cautionary tale of a design which could have made the transition simpler but did not.

IPv6 cannot be backward-compatible with IPv4 in the way UTF-8 is with ASCII. Any argument built on that comparison reflects a misunderstanding of the protocols and leads to flawed conclusions.

You literally missed the most important part:

"A transition from IPv4 to IPv6 seems far more easier especially since we already have 77% of people on IPv6."

So to the extent they're aware of the "issues" you bring up they're already on top of it.

ISPs providing IPv6 connectivity out of the box does not equal software and internal devices doing the same.

Someone should’ve thought about the UX of IPv6 before declaring it to be “the way”. It’s like having to learn Klingon just to setup your printer. IPvNext could sort that out… maybe it’s time to consider moving on.

IPv4 has been "in crisis" for the entire 20 years I've worked in tech and we seem to be managing alright. Not to say things can't be better or we shouldn't try to improve. But I'll be surprised if v4 isn't still the default for most use cases in another 20 years.

That's because the Internet is basically broadcast TV 2.0 so no one cares about having public IPv4's at home as long as they can get to their memes and streaming. Great job, we took something that was meant to be a next frontier in humanity and let anyone connect with anyone else without gatekeepers/intermediaries and turned it 21st century brainrot troughs. Perhaps a society not in slow intellectual decline would have chosen otherwise.

I am behind cgnat but have a native ipv6 /64 at home. I've got a great fibre connection (2G5) and everything "just works". I can host on ipv6 native machines and see them from anywhere in the world that has native ipv6 access.

The trouble is that 1) my employers do not have native ipv6 access; 2) neither does my mobile connection; and 3) really nor do a lot of my friends. Moreover, 4) if you browse a website from a native world-reachable ipv6 address, you're fingerprinted by it and it's overwhelmingly unique to you. So, it doesn't really work for hosting, and I don't get any direct benefits from it.

Instead I have a vps with a public ipv4 address and have a router that creates a wireguard tunnel to it. The reverse proxy works great over ipv6 and I am now in a position where I can forward ports and have direct connections -- albeit with hugely increased technical complexity. Ipv6 has many great ideas in it. If it's universally used it might just catch on...

Wait, why couldn't it?

Just split the address into two 32-bit chunks (call the top word the "pool", bottom word "address") and assign the full IPV4 range to pool 0x00000000. Done.

People claim this all the time, but every time I push I discover they have no clue how networks work and just handwave away as "easy" or "details" the very reasons people who understand networks say it can't work.

Yep. Translation technologies like NAT64 and company basically as good a job as can be hoped for. And they're quite good nowadays!

But to stick with the ASCII->UTF-8 comparison: how would you have done the transition if you had to stay within ASCII's size of 7 bits?
