You need NAT (or something else that is worse in some respects, like port forwarding) in any situation in which your subnet is given only one address upstream, even if it is an IPv6 address.


If your ISP doesn't do PD with v6, their implementation sucks. Even my crappy 6rd setup from CenturyLink gives me iirc an entire /48.


Many ISPs suck. That’s not controversial.

We have to deal with the world we live in, not the world we’d like.


That's why variable length SLAAC has been proposed

oh no

No we don't. Some choose to just put up with shittiness, others enact change.


Priorities. I don't have to put up with PPPoE in 2023, but it's a hell of a lot less expensive than pulling munifiber to my garage (and the monthly fees for munifiber are higher too, so there's no point in time where it makes economic sense), and consistency and stable addressing is currently winning over the promise of 5g/leo satellite.


Sure, but you're choosing that prioritisation. It's not being forced on you.


I'm not even sure if you and GP agree or disagree.

As for me, I want IPv4 to stay forever. It works for me and I don't see any reason to spend time and migrate to something else.


OP here.

Your "ISP" is a sysadmin at work who gives you one address to your cube.

You otherwise like the work and the team, and the compensation is fine.

Now what?


> Now what?

You advocate for change. You make the case.

You might not win the battle, but you're by no means forced to accept the status quo. The more who fight the battle, the more win. The more win, the faster progress, which benefits us all.


I set up NAT, I move on.

If you can solve a problem technically, without involving people, that is best.


Yeah, but there's no reason to do that with IPv6
