    IPv6 without stateful DHCP can reveal your device since the latter half of the address is comprised of your device’s MAC address. Unless you use randomized MAC, I guess. There are some other advantages because they are globally unique. NAT, as you mentioned, is a big one. Anycast is another, but I don’t fully understand how that works. It somehow assigns the same IP to multiple hosts for redundancy.

      Wow, I didn’t know that it could reveal your MAC. I set all my devices to randomize, but I doubt most people know to do this. Did a cursory bit of research and it seems newer configurations avoid this at least.
