I’m a bit concerned about SLAAC’s metadata leakage. Sending out many of my devices’ MAC addresses to the world isn’t exactly the best for privacy. My key devices like laptop and phone use MAC randomization, but I have a ton of other stuff that doesn’t.
That leaves DHCPv6, which won’t work with any android devices or chromebooks.
Damn, that’s a straight WONTFIX, too since 2014. Lots of religious argument in there, maybe I’m reading all that tonight.
Modern operating systems don’t use the MAC address for SLAAC. They generate a completely random address. You can choose a stable address or a temporary one that will change frequently for more privacy. You can also use both, IPv6 allows multiple addresses on one device.

Thanks for answering my questions.

Great to know, thanks!
