I host some services at home, mainly targeted at friends and family.
Some are IPv6-only, because it's much easier to manage from my side. I whish I could add an A record for these that pointed to a reserved IP address that would inform clients the service is IPv6-only.
For now, I just don't put any, and browsers just display a generic error. Since some DNS don't answer with IPv6 addresses, the browser couldn't even provide a meaningful error message if it tried to.
Would that be worth an RFC? What IP address should be used?
- growse 6y agoIsn'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.

- MayeulC 6y agoAh, thank you, that's quite close to what I wanted. Ideally, it would be ran by a CA to work flawlessly with web browsers. Even better if web browsers could display a message of their own, recognizing this IP address.
