Isn't the presence of an AAAA record but the lack of an A record already a sufficient indicator that the service is IPv6 only?

- MayeulC 6y agoIt should, but: * I don't know any browser or app that display a special, informative message in that specific case. * You need a DNS server that answers AAAA record to detect this. Some ISPs do not provide IPv6 connectivity, nor do their DNS servers provide AAAA records. In most places I know, especially when talking about individuals, people use their ISP-provided DNS servers.
