Dear WG, After the October 26, IETF DNSOP interim WG on DNS Error Reporting, the document editors have made the following changes to reflect the discussion:
Change 1) Due to qname minimisation, the reporting agent may not know that the reported string has been shortened. There were a few options suggested, such as adding a label counter. However, the most straightforward option seemed to be to start the reporting query with an _er label as well. Change 2) There was an observation by developers that some authoritative servers do not parse (unknown) EDNS0 options correctly, leading to an additional roundtrip by the resolver. It was suggested that authoritative servers could return the new EDNS0 option “unsolicited”. This is already the case for Extended DNS errors. We have adopted this suggestion. It was also pointed out that this kind of unsolicited behaviour can be surveyed. We believe that one such effort is underway. Change 3) There as a lot of descriptive text what implementations should and shouldn’t do, and what configurations should and shouldn’t do. This was found to be overly descriptive and pedantic, and has now been removed. There was a request to put the markdown version of the document in GitHub. This has now been placed here: https://github.com/RoyArends/draft-ietf-dnsop-dns-error-reporting <https://github.com/RoyArends/draft-ietf-dnsop-dns-error-reporting> New version: https://datatracker.ietf.org/doc/html/draft-ietf-dnsop-dns-error-reporting-01.txt <https://datatracker.ietf.org/doc/html/draft-ietf-dnsop-dns-error-reporting-01.txt> Diffs: https://www.ietf.org/rfcdiff?url2=draft-ietf-dnsop-dns-error-reporting-01 <https://www.ietf.org/rfcdiff?url2=draft-ietf-dnsop-dns-error-reporting-01> Warm regards, Roy Arends
