Query DNS for HTTPS records (alongside traditional A and AAAA queries) and, on receiving a record, trigger an HTTP->HTTPS redirect. Design doc for all Chrome DNS HTTPS plans: This feature covers just the basic query and HTTP->HTTPS upgrade part of those plans, and only for simpler cases that do not require followup DNS queries by the Chrome DNS stack.

Interoperability and Compatibility

Not directly part of the Web API, only has indirect behavior implications on the webplatform in the form of the HTTP->HTTPS redirect triggered by DNS signals. HTTPS DNS records are a feature of DNS. The spec is a draft of the IETF DNSOP working group, and while not yet a published RFC, it is widely considered stable and ready for implementation. IANA has designated HTTPS as DNS resource record type 65.

Gecko: No signal

WebKit: No signal

Web developers: No signals

Is this feature fully tested by web-platform-tests?
