The Uniform Resource Identifier (URI) DNS Resource Record
Draft of message to be sent after approval:
From: The IESG <email@example.com> To: IETF-Announce <firstname.lastname@example.org> Cc: RFC Editor <email@example.com> Subject: Document Action: 'The Uniform Resource Identifier (URI) DNS Resource Record' to Informational RFC (draft-faltstrom-uri-14.txt) The IESG has approved the following document: - 'The Uniform Resource Identifier (URI) DNS Resource Record' (draft-faltstrom-uri-14.txt) as Informational RFC This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Pete Resnick. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-faltstrom-uri/
Technical Summary This document describes the already registered DNS resource record type called the Uniform Resource Identifier (URI) RR, for publishing mappings from hostnames to URIs. Working Group Summary The document was discussed briefly in the Apps Area WG and the DNSOP WG, and the now-closed DNSEXT WG, with no significant objections. The registration for the new resource record type was already approved by the expert reviewer a few years ago. Last Call discussion turned out to be lively, and the conclusion was that this should simply be an Informational document and not Standards Track. Document Quality The draft is pretty simple, and has been rolling around for many years with only minor modifications. It is already implemented in some widely-used DNS software. There has already been an INT-DIR review of this document. Last Call discussions centered around the document's focus on using this for the web, which was deemed problematic, both regarding security considerations and the fact that there is unlikely to be deployment in that area, and on its attempt to introduce a new NAPTR flag. Security Considerations were updated accordingly, the example was changed, and the discussion of the new NAPTR flag was removed. There is consensus around this being a good informational description of the RR. Personnel Paul Hoffman is the document shepherd. Pete Resnick is the responsible Area Director. RFC Editor Note Please make the following changes: Section 1: OLD Historically, uses of the DNS to map a domain name to a URL have relied on the NAPTR RRTYPEs and then on the DDDS [RFC3401] application framework with the DNS as a database as specified in RFC 3404 [RFC3404]. NEW Historically, uses of the DNS to map a domain name to a URL have relied on the Naming Authority Pointer (NAPTR) RRTYPEs [RFC2915] and then on the Dynamic Delegation Discovery System (DDDS) [RFC3401] application framework with the DNS as a database as specified in RFC 3404 [RFC3404]. Section 2: OLD Applications MUST know the specific service to prepend the hostname with. Using repetitive queries for URI records MUST NOT be a replacement for querying for NAPTR records according to the NAPTR (DDDS) or S-NAPTR algorithms. NEW Applications need to know the specific service to prepend the hostname with. Using repetitive queries for URI records is not a replacement for querying for NAPTR records according to the NAPTR (DDDS) or S-NAPTR algorithms. Section 7: OLD will effectlyely lead to a downgrade attack. NEW will effectively lead to a downgrade attack.
