MDNS: Additional records from query

Open casperjuul opened this issue 3 years ago • 1 comments

Hi,

Is it only possible to readout additional records when the received packet is a response ? mdns_flags = 0x8000. I can't find anything in rfc that says query can't contain additional records so is this intentionally?

Hi @casperjuul Sorry for the late response. In RFC6762, Section18.14, query message may contain Known Answers in the Answer Section, but there is no other info that mentions query can contain additional records. In RFC6763 Section 12, server/responder should include additional records in response, it is also not for query. Did you encounter any issue for query?
