I-D ACTION:draft-ietf-dnsop-reverse-mapping-considerations-04.txt

A New Internet-Draft is available from the on-line Internet-Drafts 
directories.
This draft is a work item of the Domain Name System Operations Working Group of the IETF.

	Title		: Considerations for the use of DNS Reverse Mapping
	Author(s)	: D. Senie, A. Sullivan
	Filename	: draft-ietf-dnsop-reverse-mapping-considerations-04.txt
	Pages		: 14
	Date		: 2007-7-3
	
Mapping of addresses to names is a feature of DNS.  Many sites
   implement it, many others do not.  Some applications attempt to use
   it as a part of a security strategy.  This document outlines what
   should be taken into account when deciding whether to implement
   reverse mappings of addresses to names, suggests that site
   administrators implement reverse mappings if there are no strong
   considerations against such mappings, and provides considerations to
   be taken into account when using reverse mappings.

The draft mentioned above reflects the contemplated changes that I
sent to the list in the time since the -03 draft.  It is mostly
unchanged from the -03 submission, but it _does_ include the
contemplated reference to RFC 1912, as well as an explicit remark
(occasioned by Mark Andrews's and Dean Anderson's comments) that
overzealous interpretation of RFC 1912 can have deleterious effects
(this latter at the end of section 4.4).  I take that to be a (small)
substantive change in the document that diverges from the outlined
list of planned changes, so I am drawing attention to it.

I will note also that we did _not_ include an exhortation to
implement DNSSEC in the Security Considerations section.  We did not
receive much in the way of feedback on the suggestion one way or the
other.  Because such an exhortation seems to be merely a request that
everyone implement something already elsewhere defined, we thought it
might set a bad precedent.  The document already includes references
to the RFCs in question, so operators can presumably draw their own
conclusions.

As always, comments are solicited.  It is our fervent hope that we
have either adequately addressed the comments we have received in
this draft, or explained on the list why we did not discuss those

	Title		: Initializing a DNS Resolver with Priming Queries

Re: Request for IETF69 DNSOP Agenda Items

I would like to have the WG discuss taking up my draft 
(draft-anderson-reverse-dns-status) as a WG document.

Thanks,

Re: draft-ietf-dnsop-resolver-priming-00.txt


| 3.2.  Completeness of the Response
| 
|    A resolver SHOULD consider the address information found in the
|    additional section complete for any particular server that appears at
|    all.  In other words: if the additional section only has an A RRSet
|    for a server, the resolver SHOULD assume that no AAAA RRSet exists.
|    To ensure equal availability the A and AAAA RRSets should have
|    identical TTL values at the authoritative source.

The last part doesn't make much sense because client queries can cause
the A and AAAA TTLs to drift apart anyway (cf. section 3.1).

I haven't seen alternative text proposed; here's some: 

  The set of name servers for a zone should be reachable via all
  versions of IP (e.g. IPv4 and IPv6) in common use.

I think that expresses what you wanted, and also gets rid of the
"transport protocols" nit that Rob noted.  (To emphasise, though, this
whole discussion is a nit as far as I'm concerned; I'm happy to see it
go ahead without the change.  It seems like an editorial matter to me.)

[Fwd: I-D ACTION:draft-crocker-dns-attrleaf-03.txt]

Folks,

If you are looking for a cliche, how about:  better late th, an never?

This is revised based on original presentation about dns-attrleaf, in order to
document it as a starting point for working group discussion.

I suppose, in fact, this should have been submitted as
draft-ietf-dsnop-attrleaf, but it was too late for a new draft posting.

I know at least one participant has an alternative data model to propose for
registration, and am hereby encouraging him to submit his comments, in order
to get group discussion going.

Selection of the "Design team" for NCP
(http://www3.ietf.org/proceedings/07mar/minutes/dnsop.txt). It was
planned in Prague but not actually done so I suggest, this time, to
set up the team and its mailing list / issue tracker / whatever on the
stop and to have a first meeting the same evening.

     Phil Regnauld, Stephane Bortzmeyer
     <http://www3.ietf.org/proceedings/07mar/slides/dnsop-0.pdf>

     Stephane Bortzmeyer presented the draft.

     Joao Damas says that the ISC will implement something like this and if
     it's interoperable, that would be even better.  Joe Abley said he is not
     convinced we need a protocol, but rather an "arrangement".  
     Mark Andrews said he thinks we definitely need a protocol and
     Lars Johan Liman agreed and suggests an extensible framework.

WGLC for <draft-ietf-dnsop-respsize-07.txt>

Dear WG,

the draft <draft-ietf-dnsop-respsize-07.txt>, "DNS Referral Response Size
Issues" has been on our plate for quite a while.  After the Prague meeting,
four people have come forward with a review, all but one supported the
document with minor changes suggested, the fourth reviewer put more strength
in his concerns which were focused on particular paragraphs, not the
overall structure or direction of the draft. There was not much discussion
or contention w.r.t. the proposed text changes.
We have still three people left on our WGLC volunteers list, so to save
another editing cycle, this message starts a

	Working Group Last Call on <draft-ietf-dnsop-respsize-07.txt>
	ending Wednesday, 2007-08-22 12:00 UTC

Please review the draft and the list thread starting 2007-05-07 and comment
on this list, preferrably including proposed text if you'd like to see
changes. Our charter lists this document as aiming at "Informational"
status.

We will have one more version of the draft to incorporate current and WGLC text
changes and NITS review, the -08 to go to our AD.

Thanks,
  Peter
