I got IPv6 working on my home network. My only issue with it was privacy. And not the privacy addresses that theoretically randomize the host portion of the address. On IPv4, when I do a geoip lookup on my IP, I see a dot about a mile away from me indicating the part of town I'm in (already creepy). On IPv6 the dot was on my block. So I scrapped IPv6 mostly, and have ProtonVPN on my computer with only gaming bypassed. I think MullvadVPN has IPV6 support.

My whole city is behind NAT (IPv4), it's like small tor. I think IPv6 was supposed to work the same: the whole city should be in a single /64 network, otherwise address randomization doesn't provide k-anonymity.

  I feel like we're past the point where IP address randomization practically provides reasonable privacy: Unless you use a new address per connection or at least site visited, data brokers will just collate your data on their backends. Solutions providing per-flow privacy like MASQUE seem like a more promising approach.

    Using a common IP address is laundering your traffic with everyone else's, which makes that IP data less valuable. I refresh my connection several times a day.

      But serveral times per day is not enough if you visit at least one site that both knows who you are and is willing to sell your data to a data broker. Then all other sites that you've browsed to anonymously can buy the information "who had IP x on day y" and still know who you are.

That is just a difference in geolocation. Maybe because IPv4 addresses tend to change more frequently than IPv6 because there are fewer of them. There is little practical difference in privacy, with IPv4 leak the address for house, with IPv6 leak the prefix for the house. Address randomization means that can't track devices inside the house over longer periods. The privacy addresses happen by default, you would have to disable them deliberately.

The geoip depends on how much your ISP discloses as far as I know? I see one of three answers for my IP addresses (V4 or V6): - The capital city of the country I live in - The town my ISP's head office is in - null, null I don't live in any of these locations :) The latter is actually increasing a lot. I wonder if I turn adblock off will I get ads for singles in null island
