I don't run IPv6 on my home network. I try it about once a year, enabling it at the router (it's already enabled on my laptop). And then random stuff just doesn't work. Various websites hang, various widgets just don't load, etc. Then I turn it off and everything gets better again. I'be been too lazy to diagnose why exactly it doesn't work, I just figure it's easier to run with it off. At some point a website I really want to access will require IPv6. Hopefully by then whatever is broken will be fixed.

Before I switched ISPs a few weeks ago to one without IPv6, I was with an ISP with IPv6 (dual-stack) for about five years and had zero problems. In fact it worked 'too well' initially: when I was still IPv4-only I had put a bunch of Facebook domains in my iMac's /etc/hosts file pointing to 127.0.0.1 so that all those little icons would stop loading. At some point I noticed they were back. After some head scratching over a day or so I realized that Facebook was IPv6-enabled, and so the icons were loading because AAAA records were working. Adding ::1 for Facebook in hosts fixed things.

    One of the security issues with dual stack. Your attack surface is twice the size, and human error means you are more vulnerable. Still unsure of the benefit of dual stack, but there are numerous costs.
- jandrese 3y ago
  You have some misconfiguration on your local network. It's hard to tell from your description, but I'd guess maybe you don't have the firewall rules configured for IPv6 or something. Breakage is extremely rare on the live web. I can't remember the last time I found a website that was only breaking on IPv6.

    The other common mistake is blocking ICMPv6 completely. This creates a really broken IPv6 stack! edit: I've been running dual-stack with Windows, macOS, iOS & Linux for at least a decade now - I think it's closer to 20 years than 10! I've never seen it be like the parent post for my personal use, but I have seen it broken like that in places I've worked with incorrectly configured routers/firewalls. edit 2: this isn't a good idea for v4 either, but it's less broken than v6!

    > You have some misconfiguration on your local network I’m sure I do. But that’s sort of the point. I only use standard commercial hardware with the default config. If that doesn’t work out of the box, what chance does someone who doesn't have my decades of networking experience have in fixing it? Granted I’m probably more sensitive than most because I know what network issues look like. Most people probably just think some things are slow sometimes. My ultimate point though is that this is probably a barrier to adoption.

      You have decades of networking experience but you are unable to get ipv6 to work, something that over 40% of internet users are using daily. [1] https://www.google.com/intl/en/ipv6/statistics.html https://www.google.com/intl/en/ipv6/statistics.html

        I can get it to work just fine. It just doesn't work as well as IPv4 and I can't be bothered to figure out why. I'm in that 40%. I use IPv6 on my phone whenever it's not in my house.

  Debian would just not run due to apt repositories being borked if ipv6 was turned on.
  - betaby 3y ago
    Which exact repo was that?
    - sambazi 3y ago
      there are thousands of debian mirrors, not that far fetched that at least one of them has broken v6
    - minimaul 3y ago
      I seem to think that the primary UK mirror (http://ftp.uk.debian.org/ http://ftp.uk.debian.org/) was problematic for v6 for a while? But these days the https://deb.debian.org/ https://deb.debian.org/ mirror is really heavily pushed, and that one seems to work just fine. edit: but this was quite a few years ago, from grepping my IRC logs, somewhere around 2016!

    My network is dual stack and all my VMs are Debian. No issues here.
  - sambazi 3y ago
    anything more concrete? i was struck by an issue in this area a few years ago and i think it was fixed by tuning gai.conf to prefer v4 because there were some repo servers that had broken v6

These are some very compelling bingo items - I’m not sure if sharing this card is having the intended effect (unless you wanted me to continue to think that IPv6 isn’t ready for real use?)

  >IPv6 isn't ready for real use Tell that to 45% of the Internet. Also, half of the bingo items there are intentionally humorous, and if you are taking those items literally (I wouldn't be able to tell, you never listed them out) - congratulations, you are part of the bingo :)

My work's VPN is horrifically misconfigured and breaks if I have IPv6 enabled, is that a good enough excuse?
