It’s true a few isps will provide you a static up but most will not.

In most implementations the end user sees no benefit from IPv6 or simply an isp using carrier grade NAT. When IPv6 first rolled out it was promoted as a way for everyone to easily obtain addresses .. reality is not so much. End user functionality crippled Or gatekeeped
Hypothetically should be to host a simple file share of let’s say photos on a desktop and share using SMB or another protocol via IPv6. No need for cloud provider / iCloud Photos, Google or whatever. Just a direct connection with a desktop that stays on 24/7. This is not the case and effort has been made to make IPv6 really more of a useful protocol to mobile isps managing large numbers of new devices.
IMO #lame
How do you tell an embedded device to push a DDNS update?
I see this as a feature not a bug. Use dynamic DNS if you need a stable endpoint here.
> The idea that a home user ca setup a desktop and share anything I want via IPV6 another person without the need for a middle man “cloud” provider just didn’t happen.
You can, you likely just need to change the default firewall settings on a typical ISP provided router.
> Corporate greed / government control have severely limited any usefulness of IPv6 at least here in the US
I don't see how either of those have to do with this.
