Re: RFC 2732 and Zone IDs

 It doesn't really bother me that it isn't covered by the latest URI syntax
 (and therefore not by IRI syntax). I must say I have largely ignored
 the whole scoped address debate, so I missed this when we did the original
 work on RFC 2732.

Brian originally made this statement in an exchange with some URI/IRI authors/experts and the IESG regarding my "discuss" position on draft-duerst-iri-10.txt. My response was:


"I don't know. A year ago, I would have said "no", but with documents on the IESG agenda like draft-black-snmp-uri-08.txt, I am taking a new view of URIs. This document defines a URI syntax that can be used for access to SNMP objects, and one of the use cases includes having a local SNMP manager that is accessed through a URI -- the URI then being translated into an SNMP request that is sent to the agent via SNMP.

So, URIs can, effectively, be used as a programmatic interface to other applications running on the local system. In that sort of case, I think we very well might need to include scoped addresses in URIs. And, IMO, it would be better to have a standard way to do this than to live in a world where folks just insert an unencoded % and some parsers pass it through cleanly, others escape it for you and still others return an error -- which is how the current behaviour of URI parsers has been described in this thread."

BTW, I don't think it was a mistake to omit this when RFC 2732 was published, as the IPv6 Scoped Address Architecture (which defines zone IDs) was only recently approved by the IESG for publication at PS.

In any case this is a dead duck, unless the IESG wants to recall 2396bis
from the RFC Editor, which seems absolutely unjustified to me.

The discussion with the URI/IRI authors doesn't seem to be moving in the direction of recalling 2396bis. It seems preferable to write a new document that defines an IPv6 address encoding that includes a zone ID. This could be done under the IPvFuture mechanism described in 2396bis.


I'm certainly willing to let the URI/IRI folks figure out the best way to fix this problem, but I don't understand how the fact that 2396bis is in the RFC editor queue makes this problem a "dead duck". In fact, I'm not sure I understand what "this" is referring to in the sentence above.

I don't know exactly where this will end up, but given the fact that 2396bis will obsolete RFC 2732 when it is published (which I didn't realize when I started this thread), I agree that an update to RFC 2732 doesn't make sense.
