I don't want IPv6. Why would I? It's like a permanent global cookie. You're uniquely tagged and identifiable on every website you visit.

>it's in their best interest to ensure users can't host services without them.

They'll just keep blocking port 25. IPv6 won't change anything with regards to self hosting.

My OS gives me IPv6 privacy addresses out-the-box which rotate every few hours.

The prefix is your globally unique identifier. "Privacy addresses" provide zero privacy.

“Privacy addresses” are named because in the beginning, your auto-generated IPv6 would incorporate your hardware MAC address verbatim, and many people consider the MAC address to be PII.

Hard to believe the committee thought that was a good idea.

Almost every modern OS enables IPv6 privacy extensions, ie address randomization, by default.

On the last 64 bits, yes. On mobile phones, the first 64 bits may be fixed. This was something I argued against when I was at Vodafone Group, but didn't get any traction. That was a while back, but I'd assume that this is still the case, and that mobile phone addresses can be used for tracking.

Just like IPv4, then. Ultimately some part of the address has to identify the physical router.

No, not just like IPv4. My IP address is 192.168.0.23 right now, as are millions of others. Add in CG-NAT from my ISP and I do not have a globally unique identifier.
