This is a huge problem. We need to start our own ISPS. Municipal owned or alongside a microgrid co-op are good options

Use hostnames and dynamic prefixes or addresses don't really matter. Haven't had an issue in years and my last isp changed prefixes multiple times a week. I mean technically it would not be available for five minutes when IP changes but never noticed.

If you only care about having a static IPv6 address take a look at TunnelBroker by Hurricane Electric. They give you free /48 IPv6 blocks tunnelled through their network. Words of warning though: 1) some ISPs block using this service (prevent the tunnel from working), 2) in my experience I’ve seen high latency due to weird routing, 3) those IPs ending up on blocklists due to abuse and 4) the tunnel is unencrypted so traffic between you and Hurricane Electric is trivially intercepted, though if that was a problem in the first place then you wouldn’t be hosting from your home network anyway so this is mostly moot.

Capitalist institutions push capitalism? What kind of world is this!

My dynamic IPv6 prefix hasn't changed in a couple of years. It only changed because I reset the router config and that changed my DUID. That's good enough for everything I host. I don't even bother with dynamic DNS anymore.

I wouldn't bother with trying to host an email server from a residential connection though. Even if you can get your ISP to open port 25 for you, many email servers won't accept mail from residential IP addresses.

I wonder how often the assigned prefix changes with most of the regular ISPs. I'd have to look someone else's router since I'm still stuck on an old contract. But I believe what I saw with some of the regular consumer contracts: the prefixes stay the same for a long time. You could just slap a free DynDNS service on top and be done with it.

But yes, I think this used to be the promise... We'd all get IPv6 and a lot of gadgets like NAS systems, video cameras and a wifi kettle and they'd be accessible from outside. Instead of that we use big capitalist cloud services and all the data from the internet of things devices has some stopover in the China cloud.

IPv6 costs money to implement so it doesn't happen without good reason.

For ISPs you need many options so that one company can't take all the business. In my area competition is steep so fiber is cheap. In rural areas I'm personally interested in community or small ISPs. Surely some people could get together and make something better.

Starlink gives me an ipv6 its not static as such but a dynamic DNS can solve that issue. My ISP issue is that my mobile provider doesn't give me an ipv6 at all so I can't route to my home server without a gateway to proxy.
