IPv6 just turned 30 and still hasn't taken over the world

Turn off temp addresses. If your prefix changes then use ULA addresses.

I suppose I could have said how.

Windows in powershell:

  SetNetIPv6Protocol -UseTemporaryAddresses Disabled
  SetNetIPv6Protocol -RandomizeIdentifiers Disabled

Linux:

  sysctl net.ipv6.conf.all.use_tempaddr=0

or in NetworkManager config file:

  ip6-privacy=0

OpenBSD:

  ifconfig em0 inet6 -temporary

Yeah. ULA and nat66 would work nicely. Except you would get murdered for asking about nat66.

I'm convinced half the ipv6 subreddit is made of people who don't actually like ipv6 and are trying to subvert it. The advice they give sometimes is just insane. "Just get a new ISP bro..."

I think a lot of people assume privacy addresses are required. You can just not mess with them. Privacy is dead anyway.
