The Mozilla page on the topic (https://support.mozilla.org/en-US/kb/canary-domain-use-application-dnsnet https://support.mozilla.org/en-US/kb/canary-domain-use-appli...) notes that:
> The use of this domain is specified by Mozilla, as a limited-time measure until a method for signaling the presence of DNS-based content filtering is defined and adopted by an Internet standards body.
Presumably that'd be the IETF, and I have no idea which committee would be working on this, if there's a draft RFC in the works, etc. But it's clear the expectation is some sort of standard mechanism will eventually replace the canary domain that yields the same functionality but in a less hacky way.
- Arnavion 5y agoThere was [1] which would've allowed websites to specify custom DoH resolvers for their subdomains, but it expired some time ago. The same authors are now working on [2] instead, which AFAICT is basically for the same thing. There's also [3] which is a way for the DHCP server to also provide DoT and DoH servers to the LAN (in addition to the usual DNS servers).
