According to Google (https://www.google.com/intl/en/ipv6/statistics.html https://www.google.com/intl/en/ipv6/statistics.html), 60% of word-wide users wouldn't be able to visit your website. In the US, it would be about ~50% of users, while in Europe it's ranging from 30% (France) to 98% (Spain) who wouldn't be able to visit the website. But yeah, I'd do what you say in the bottom of your comment. Add AAAA records and then see how many people uses ipv6 compared to ipv4 and then decide.

Sigh, so basically it's impossible to switch without shredding an already tiny audience. I'm sure it won't be a nice UX either to have a "can't connect to this IP" error in someone's browser. IPv6 has been around for so long now, I'm disappointed it doesn't have a little bit higher adoption.

  And if all else fails, you can put something like Cloudflare in front of it to handle IPv4 traffic.

    Which than you're back to paying $40+/year to ensure you don't get wiped from their "free" tier when they feel like it. Nothing is free forever.

      True, it is a temporary solution though to how long Cloudflare offers it.

      They have had a free tier since they launched over a decade ago. I think they’ve found a way to monetize that traffic or at least the data they collect on the sites they proxy because it’s survived so long.

        I think it's the same model as free antivirus. Free customers provide a lot of data to analyze and detect threats, which translates into increased value of the product to the paying customers. Also gives you a lot of traffic which you can use to test new deployments without disrupting paying customers.

      I've been on their free tier since launch. Granted, it's nothing high-traffic, but a personal website shouldn't reach any "please upgrade" thresholds.

  Might be a good idea to make a hidden request from your homepage to an ipv6 only resource. Then log how many of your visitors actually fail.

  It's a chicken and egg problem: as long as sites are available through ip4, ISPs have no incentive to provide ip6, and since ISPs often don't provide ip6, sites can't go ip6-only. One possible solution would be to provide both and throttle ip4 traffic, then better speed can provide incentive to upgrade to ip6.

I understand that Movistar, the largest Spanish ISP, is currently deploying IPv6 in beta at the moment. I expect that will trickle down to the various resellers of Movistar's network shortly after. Hopefully that will get that 98% down in the near future. :(

So if a domain only has a AAAA record, and for whatever reason a user can’t use IPv6, what sort of error message would the user see?

    >>DNS_PROBE_FINISHED_NXDOMAIN This is because your OS is not querying AAAA records. I am gonna guess that your using macos. The most common error would be a "connection time out".

      I'm not sure, but I believe I was on Windows 10 at the time. Shortly after this, I checked the appropriate boxes on my router (UDM-PRO) and my home network now supports IPv6. Passed all the tests on that website at least.

  The client shouldn't even attempt to get an AAAA record unless they have an IPv6 stack available. In that case, their client should try to look up an A record and get an NXDOMAIN error which the browser usually shows as "IP address could not be found". If the client does attempt IPv6, you'll get a stack error when trying to connect to the remote host because the kernel will reject the address family and you'll get something like "network is unreachable". Some clients will also degrade from AAAA to A on error so you'll get the NXDOMAIN error as above.

I think there’s a difference between “don’t” and “can’t”. It’s not clear to me on that page how it describes “can’t”, other than ambiguous (to me) graph labels. Is there more info elsewhere that describes the “can’t”?

  Chrome connects to google through ip6, if it succeeds, then ip6 is available, thus they gather statistics.
