You might not have noticed, but I have done a bit of IPv6 over time,
so yes, I understand. And thus: 6to4 needs to die. In flames.

This is not solved by poor-quality tunnels. All these tunnels do is
"make IPv6 look bad", so people get to learn "IPv6 has more latency, more
packet loss, and I can not even call customer support if it does not
work, so better avoid it".
This was already accepted truth 10+ years ago.
have you enabled IPv6 on something today...?
