The resistance to switch to ipv6, or the comfort with the ipv4-born address exhaustion remedies, only helps an internet of consumers, not an internet of peers that create and share. If you are behind NAT or CG-NAT, you can only consume, not create. You can't host a server, expose a port. You are at the mercy of the big fish.

My ISP is IPv4 only and I host plenty of shit and punch plenty of holes. That’s a function of my firewall not how many bits are in my IP address.

I actually made the unusual decision, last year, to go IPv6-only on a small website I operate. The reason why is that AWS changed their billing policy for public IPv4 addresses. This is a tiny website that people only access on their cell phones, so I can accept an occasional inconvenience for the marginal cost savings. I haven't heard of anyone else doing this, but I doubt I'm completely alone in trying to minimize…

On the other hand, same as you I tried IPv6-only to reduce costs but I couldn't load my website at all on my mobile.

It is the ISPs, that pretty much killed the IPv6 with their mishandled transition.

Where I'm, I can choose 1 out of 1 broadband provider available in the area. With this provider, I can either have a public IPv4 address (or several) with their CPE in bridge mode, or DS-Lite, with IPv4 CGNAT without PCP and /64 for the IPv6 addresses (i.e. no address space for subnets, no prefix distribution) AND having to use their router with the limited settings they allow.

With offers like these, is it any wonder that I stick with IPv4?

You can’t punch any holes through carrier-grade NAT (CGNAT).

I don't understand the title. What's the "but" there? IPv6 being irrelevant and moving off IPv4 being irrelevant seem like they go hand in hand, if moving off IPv4 is irrelevant then of course IPv6 is irrelevant!

Don't think about it too much, just remember that only large corporations are supposed to be peers on the internet, everyone else should be behind layers of NAT to ensure they can't become a problem.

You can, if your ISP cooperates, using PCP.

That's only true if you aren't behind CG-NAT. If you are, your firewall can port forward all it wants but it won't matter, the ISP would have to also port forward to you.

Did you miss the part about CG-NAT? Once your ISP runs out of their IP4 addresses and puts you behind a CG-NAT, you can punch all the holes you like; nothing is going to get to you.

At least not without doing fancy stuff like using an externally-hosted VPN to shuttle connections to you.
