For a few years now, I've tried enabling IPv6 at home (not exclusively, just dual stack). Every time I do, I inevitably turn it off because something breaks (usually some website that pretends to have an AAAA record but then it times out and has to fall back to IPv4). Until it's easy for nerds like me, I just don't see it taking off. So far I haven't found a compelling reason to spend the time to get it to work well, and it doesn't work well out of the box, so I see no reason to use IPv6.

I’ve been running dual stack for years, with multiple IPv6 subnets in fact, and don’t have these issues.

  That's great, but my lived experience is different from yours. Maybe my setup is broken, maybe my ISPs DNS is broken, maybe my router is misconfigured, maybe something else. The point is, I don't see a compelling reason to figure it out. Everything works just as well without IPv6, so there is no point in going through the hassle of figuring out why it doesn't work for me.

    Fair. I setup it up more for the learning experience than anything else. Yes, it was a bit of trial and error before everything Just Worked. Most of my traffic is IPv6 nowadays and this is mostly with the larger entities like Google. My biggest happiness is the NAT crutch goes away, but too few networks have IPv6 deployed for this to be a boon for me.

Yeah I have a friend at an IX, with a lot of insight into IPv6 and he's constantly "chasing" ipv6 support in his personal life. It's just not worth my time right now. And someone in this thread said the problem is not at the consumer level but at the enterprise level, BS. There is maybe 1 or 2 ISPs out of a dozen here that do IPv6 at all. Mostly it's enabled for mobile operators for some reason, maybe they need the IPs more than regular broadband operators.

  My mostly uninformed guess is that mobile providers have protections in which cgnats simply break.

    Mobile operators have a lot more client devices, and many weren't around as ISPs in the time when large allocations were being given out. Most adults have at least one phone, and many children too. Wired connections tend to be one per household.

> For a few years now, I've tried enabling IPv6 at home. Is this same-ISP or through HE Tunnel? If latter, unfortunately Cogent doesn't peer with HE (HE tried to, Cogent rejected) and if your IPv6 is through HE Tunnelbroker or your ISP peers exclusively through HE in IPv6, you'll run into problems.

I had the same experience for many years, running first Asus routers then pfSense. What finally made IPv6 bearable was switching to OpenWRT. I still have annoying IPv6 issues now and then but they're at least fairly infrequent now. Of course I don't try to do anything fancy with IPv6 like using it for services, that'll only end in tears as my ISP gives me new prefixes all the time. But yeah, it's been far from plug-and-play even with OpenWRT, and as someone who has a proper IPv4 address there's very, very little incentive to put in the effort besides the nerd factor.
