Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      The temporary ones are rotated regularly (the old ones are kept around for a while as "deprecated" to keep old sockets open)

      But the prefix alone compromises privacy.

      Depends upon how often your ISP changes your prefix. Also, the same suffix is used across all prefixes...

      ...so if it didnt' change you could track devices as they moved across networks

      Seems like instead of random suffix you could just use prefix+mac hashed with a secret.

      But it's actually useful that machines use a consistent suffix across all prefixes. I know ...:7ec4 is my router whether ULA or global

      Yes. I see the value in 2 addresses, one predictable and one not. Don't see the value in randomizing & cycling the latter.

      Because otherwise you have a unique 64-bit ID which follows your machine around across networks

      Replying to @erincandescent @oshepherd and

      No, my proposal was hash(prefix+mac+secret). Without knowing secret you can't track across networks (differing prefixes).

          but then you have different suffixes across different concurrently active prefixes

          Why is that a problem? If anything it seems like an advantage for privacy.

          Which a third party can also see if you connect to resources they control via more than one interface (e.g. VPN and non-VPN)...

          Normally VPN services would manage your assigned IP themselves

          A properly-behaving IPv6 VPN would just allow the normal IPv6 auto-selection of address, no?

          This depends upon the working model of your VPN. VPNs are also (for maximizing privacy) one of the cases where IPv6 NAT may make sense
