Description
I'm getting multiple reverse DNS lookup queries, but mdns-sd
is not responding to them. As a result, my other device could not resolve and connect to the mdns service.
Here's the log I'm getting
question: DnsQuestion { entry: DnsEntry { name: "155.1.168.192.in-addr.arpa.", ty: 12, class: 1, unique: false} }
Is mdns-sd
supposed to handle those queries? The RFC mentioned "reverse address mapping"[1] made me think this is pretty standard and expected. But I'm not sure if mdns-sd
itself should handle those queries or something else should.
I could work on a PR if this is needed in mdns-sd

Currently
mdns-sd
does not handle reverse DNS lookups mainly because it's not normally needed for "service discovery". And, it seems the RFC only mentioned the link local addresses reverse lookups sent to mDNS, not private network addresses like192.168.0.0/16
in your example.The RFC section is fairly short. If you have other pointers about what mdns servers support regarding reverse lookups, or more details about your use case, it will help me to better understand if it fits in
mdns-sd
