    IPv6. Lack of IPv4 addresses it’s a problem, specially in poorer countries. But still lots of servers and ISPs don’t support it natively. And what is worse. Lots of sysadmins don’t want to learn it.

      My university recently had Internet problems, where the DHCP only leased Out ipv6 addresses. For two days, we could all see which sites implemented ipv6 and which didn’t.

      Many big corpo sites like GitHub or discord Apperently don’t. Small stuff like my personal website or https://suikagame.com do.

      Lots of really large sites are horribly misconfigured. I had intermittent issues because one of the edge hosts in Netflix ‘s round robin dns did not do MTU discovery properly.

        My isp decided to put me behind a CGNAT and broke my access to my network from outside my network. Wanted to charge me $5 a month to get around it. It’s not easy to get around for a layman, but possible. More than anything it just pissed me off that I’d have to pay for something that 1 day ago was free.

            Set up a reverse proxy on another machine (like one of those free oracle cloud things). I can’t go into detail because I don’t know exactly how. I think cloudflare also has options for that for free. Either way it’s annoying.

              Cloudflare tunnel, and its alternatives, such as localXpose, altho the privacy is probably questionable, and a many of them require a domain.

          NAT is not for security, that’s what the firewall is for. Nobody can access your IPv6 network unless you allow access through the firewall.

                If computers connect to others through the internet, the IPv6 address can reveal how many computers there are on the local network, and if certain traffic to different destinations are coming from the same computer, but also if one of the computers has gone offline but then resumes from sleep/hibernation.
                To me their comment means they want to avoid that, and I agree, I want to avoid that too. To fix these, I would need to configure NAT on my router for IPv6.

                Yes IPv6 address privacy extensions help somewhat, but

                • computers won’t use a different v6 address for every distinct destination, they will just start using a new one from time to time
                • computers won’t stop using the old v6 address immediately after wakeup

                With v4 addresses these did not really matter, because everything was being sent from the same public IP, and and outside observer could only see what a “network” is doing collectively. But with v6 an address identifies a computer, across websites/services. Even if it’s just for a "short’ time, even if the address is randomized.

                  If you want privacy, you need some kind of VPN or onion routing. Even if everything you list were correct, the difference between IPv4 and 6 for privacy would be marginal.

                    I don’t think this is so black and white. I’m a regular tor user, but so often it’s not worth it to load webpages through a dial-up connection, and then there are the sites that block access for tor users for some reason.

                    Even if everything you list were correct

                    Which parts weren’t?

                    the difference between IPv4 and 6 for privacy would be marginal

                    I disagree

          No. Stop spreading that myth. NAT does fuck all for security. If you want a border gateway, you can just have a border gateway.

      Say this to my very large Canadian ISP who still doesn’t support IPv6 for residential customers. Last I checked, adoption in Canada was still under 50%.

        50%?? I fucking wish. In Spain we are at 5%. I finally got IPv6 in my phone this year, but I want it in my home, which is still only available as IPv4 even if they’re the same ISP.
