    I think that between ipv4 and ipv6 the only thing that changes is how the ip is composed (AKA: only numeric vs alphanumeric)

      The addresses are longer (32-bit) and hexadecimal so you have sixteen digits 0-F. It also doesn’t require NAT and has native IPSec, whereas ipv4 requires addons. There are probably other differences, I hate networking.

        i hate networking

        I feel you

        Also, thank you for the info, i just knew about the 32 bit thing!

        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.

        I doubt, in the end it can maybe say “yeah you are definetly in that specific region/province in that country” but nothing more, i think it may be a little more precise than IPv4 because they will not assign you the IP that someone already has unlike IPv4

          Uh okay lol. Like I said, I don’t know much about ipv6, which is why I’m asking questions. I’m not a networking person… lots of experience with MGRS and geospatial systems though. More digits = more precision in that world. I suppose there could be an equal number of regions that ipv6 ranges map to, just more addresses per region, so same precision as ipv4?

          Anyway, you particularly should not explain it if you’re worried, thanks.
