This is in effect a > requirement that every validating stub (or resolver? I dunno) be > upgraded to support homenet. https://tools.ietf.org/html/rfc7686 dated October 2015 did this too: 3. Name Resolution APIs and Libraries: Resolvers MUST either respond to requests for .onion names by resolving them according to [tor-rendezvous] or by responding with NXDOMAIN [RFC1035]. 4. Caching DNS Servers: Caching servers, where not explicitly adapted to interoperate with Tor, SHOULD NOT attempt to look up records for .onion names. They MUST generate NXDOMAIN for all such queries. 5. Authoritative DNS Servers: Authoritative servers MUST respond to queries for .onion with NXDOMAIN. >> The .homenet queries should never reach real DNS servers > > But they're going to. Of course.

But any answer it gets makes no sense anyway, as it doesn't have the actual required data of the real local .homenet zone. So whether you give a NXDOMAIN or SERVFAIL or return an A record with 127.0.53.53 doesn't really matter, whether you are 8.8.8.8 or 216.146.35.35. I guess the only possible exception to this is if the device in the .homenet got multiple DNS servers from DHCP, and only one of them and not the first one handles .homenet properly. Of course that's a pretty broken setup to begin with, so I'm not too worried about breaking that more. Paul
