You already have a public IP address the only difference is if you have a rotating IP address which is orthogonal to IPv6. The only difference is most ISPs rotate IPv4 but not IPv6. Heck IPv6 allows more rotation of IPs since it has larger address spaces.

IPv6 can "leak" MAC addresses of connected devices "behind the firewall" if you don't have the privacy extensions / random addresses in use. There are a number of footguns for privacy with IPv6 that you need to know enough to avoid.

  Privacy extensions are enabled by default on OSX, windows, android, and iOS: https://ipv6.net/guide/mastering-ipv6-a-complete-guide-chapter-6-privacy-extensions-hiding-in-plain-sight-with-ipv6/ https://ipv6.net/guide/mastering-ipv6-a-complete-guide-chapt... On Linux, I think the defaults are left up to the distros so there is a chance of a privacy footgun there. Hopefully most distros follow the example set by Apple and Microsoft (a sentence I never thought I would write...)

    They are now - I'm not sure when they implemented them but I know Windows at least would do some really stupid stuff very early on.

      Aren't we talking about now? No one is saying we should have activated IPv6 in its first iteration.

  All desktop/mobile OSes today use "Stable privacy addresses" for inbound traffic (only if you are hosting something long-term) and "Temporary addresses" for outbound traffic and P2P (video/voice calls, muliplayer games...) that change quickly (old ones are still assigned to not break long-lived connections but are not used for new ones).
