Forwarding this along to reach more of the AFS community. I wrote back and said that I agreed with the closing of the registry and would be very surprised if anyone objected or anticipated further AFSDB record type registrations, but that I'd pass along any objections.
--- Begin Message ---Russ, you might recall that we were in contact during the draft stage of your RFC 5864, "DNS SRV Resource Records for AFS", regarding DNS specifics and some editorials. That RFC already says in its Abstract, "This document ... ... ... [It] updates RFC 1183 to deprecate the use of the AFSDB RR to locate AFS cell database servers and provides guidance for backward compatibility." This is further elaborated upon in the body of the RFC. You also might be aware of the existence of the IANA Registry named "Domain Name System (DNS) Parameters", which contains a sub-registry entitled "AFSDB RR Subtype". Currently, the IANA policy for that sub-registry is specified in Section 3.1.4 of BCP 42, RFC 6195. In the DNSEXT community (WG is bound to be closed), there is a project underway to revise that RFC, and Donald Eastlake (copied) already has sumbitted an rfc6195bis draft. I have suggested to also re-consider the rules for the "AFSDB RR Subtype" sub-registry at this opportunity, based on my knowledge of your AFS SRV usage RFC. That sub-registry has, since its conceptional inception by RFC 1183, never seen any IANA assignment of new code points, and I very strongly suspect that the AFS community will not see the need or desire to get any new code points assigned there any more. Therefore, I have proposed to declare that sub-registry as "closed" in the future update to RFC 6195. It could also be tagged as "Historic", with a pointer to RFC 5864. This message serves to poll the AFS community whether such action makes sense and is agreed upon, using you as a kind of (inofficial) "liaison" to the AFS community. You may forward this message (or suitable excerpts of it) under the IETF "Note Well" conditions to third parties that you want to contact/poll to this end. For your convenience, here is -- slightly beautified for clarity and better fit into email and draft text -- the current snapshot of the sub-registry: -------- snip -------- Registry Name: AFSDB RR Subtype Reference: [RFC6195] [RFC1035] Registration Procedures: Range Decimal Hexadecimal Registration Procedures ----------- ------------- -------------------------------------- 0 0x0000 Standards Action 1-65279 0x0001-0xFEFF IETF Review 65280-65534 0xFF00-0xFFFE Private Use 65535 0xFFFF Standards Action Registry: Decimal Hexadecimal Description Reference ----------- ------------- -------------------------------- --------- 0 0x0000 Reserved [RFC6195] 1 0x0001 Andrews File Service v3.0 [RFC1183] Location Service 2 0x0002 DCE/NCA root cell directory node [RFC1183] 3-65279 0x0003-0xFEFF Unassigned 65280-65534 0xFF00-0xFFFE Reserved for Private Use [RFC6195] 65535 0xFFFF Reserved [RFC6195] -------- snip -------- I envision the future content of it might look like this: -------- snip -------- Registry Name: AFSDB RR Subtype Reference: [RFC6195bis] [RFC5864] [RFC1183] [RFC1035] Registration Procedures: This registry is closed after RFC 5864 has deprecated the AFSDB Resource Record, and hence no more registrations shall be allowed.
