A New Internet-Draft is available from the on-line Internet-Drafts
directories.
This draft is a work item of the Internet Architecture Board Working Group
of the IETF.

	Title		: Architectural Considerations on Application
Features in the DNS
	Author(s)	: O. Kolkman, J. Peterson, H. Tschofenig, B. Aboba

While the principal purpose of the Domain Name System (DNS) is to
   translate Internet domain names to IP addresses, over time a number
   of Internet applications have integrated supplemental features into
   the DNS to support their operations.  Many of these features assist
   in locating the appropriate service in a domain, or in transforming
   intermediary identifiers into names that the DNS can process.

Re: FW: I-D ACTION:draft-iab-dns-applications-00.txt

Hi Richard, folks,
 ... and you're surprised, given the authorship ?)p

This is a good document, it is needed, and I don't read it that states that ENUM
is a bad idea.

Seriously, this had to be shipped today as it's a -00 draft, so it has some rough edges.

My initial notes on the draft are:

- In 3.1, the end of the second sentence on page 8 "needs work".

- The second sentence of section 3.3 on page 9 also needs work; 1464 applied
  the TXT record that was defined in 1035 for use for arbitrary data. 1464 did
  NOT define the TXT record.

- The last sentence in 4.1.1 on page 12 has "like" when I'd expect "likely".

- The first sentence of 4.2 uses "surfaced" in a slightly odd way; maybe "raised"
  or "exposed"?

- in section 4.2 on first paragraph of page 13, void should be replaced by unused.
  (draft-ietf-enum-void is ancient; the last one was draft-ietf-enum-unused-04.txt).

- The second sentence of the second paragraph of 4.4 on page 14 starts with a typo
  -- should be "In".

- being picky, the second "bullet" of section 5 on page 16 could replace "are only
  depended on" with "only depend".

Re: FW: I-D ACTION:draft-iab-dns-applications-00.txt

Hi Rich et al.

Let's look at the bright side of draft-iab-dns-applications-00.txt:

Finally we have the concerns expressed in written, and thus a much better 
basis for future discussions concerning any ENUM extensions (including 
E2MD).

Hopefully, with this document we can finally get rid of an odd form of 
communication, which was "conveyance of concerns by Grey-Beard-Proxy".

cheers,
  Bernie

PS: I'll try to figure out, on which list draft-iab-dns-applications is 
to be discussed, as the ENUM list is certainly too narrow for this problem 
space.

Which mailing-list for draft-iab-dns-applications-00?

Dear authors of draft-iab-dns-applications,

draft-iab-dns-applications has raised some interest within the ENUM 
community. First discussions took place on the ENUM WG mailing list.

I believe the ENUM WG mailing list is too narrow for this problem space. 
May I ask you which mailing list this document is meant to be discussed?

Unless we get further instructions from you by the end of this week, we'll 
assume that the right place for discussing draft-iab-dns-applications is 
<ietf <at> ietf.org>.

We are looking forward to your answer.

cheers,
  Bernie, co-chair of the ENUM WG

Re: Which mailing-list for draft-iab-dns-applications-00?


Hmmm... good question.

I would think that a DNS specific list is to narrow as well. The apps area list may be a reasonable place but
that would miss out on a lot of DNS folk. Because of the cross area nature it is probably best to stick to the
IETF list (a technical discussion for a change).

Trilogy and IAX draft

Folks,

I have just requested the approval of the last draft of the ENUM
trilogy. I would like to thank the authors of the three drafts for their
work on the last phases of the process.

At this point, the next step for the WG is to revise the following draft
so that it is compliant with the ENUM trilogy we have just approved.

Thanks,

Re: FW: I-D ACTION:draft-iab-dns-applications-00.txt


Lawrence,

Thanks for these notes. Your editorial concerns will be fixed in the next revision.

I’m not sure that dns-applications would be the right place to address Google’s pubic resolver, as the scope of this document is really the interplay of applications and the DNS, and at least off the top of my head I don’t see how the Google resolver is salient to that. In much the same way that iab-dns-applications does not rule out DKIM’s use of credentials in the DNS, initially I don’t think it should rule out the keyassure work either, which in my opinion could turn out to be useful, although there are also paths where it could turn out not to be useful.

The draft certainly does not suggest that HTTP and DNS are the same – merely that HTTP (or really any query-response protocol) can emulate the query-response semantics of the DNS. Obviously the two protocols are otherwise very different.

I think I do agree that the second bullet in the second set of bullets on page sixteen doesn’t capture what we meant here, though instinctively there must be some discouragement of excessive recursion. We’ll try to find a more exact way of stating that which doesn’t seem to ban CNAME. We do want to preserve concerns about redirecting between names in the DNS without DNSSEC, though.

While there are alternative technical solutions to many of the practices discussed in dns-applications, the issue the draft raises with send-n is its “predictive” quality, the practice where one node in a tree tells resolvers about the the state of nodes down the tree and the resulting synchronization issues. Perhaps there are ways to approach send-n in the DNS that don’t exhibit this quality, but perhaps there are ways to do it outside of the DNS entirely which require a lot less imagination.

The draft doesn’t attribute the story of ringtones in the DNS to any particular source, and perhaps it is apocryphal, but that doesn’t exempt it from serving as an illustrative example of excessive data in the DNS.

- being picky, the second "bullet" of section 5 on page 16 could replace "are only
  depended on" with "only depend".

- missing closing parentheses missing in third sentence of first paragraph on page 18.

----

I await with interest the IAB's comments on the Google resolver proposals (perhaps on
page 12) and also on the keyassure work (apparently on page 17, if I decode it correctly)
-- after all, Phil *might* (eventually) get carpal if he's the only one to fight those
evil people.

There are places where the authors' dry sense of humour made me laugh:

- http (or TLS) is the same as DNS -- on page 17, second paragraph,

- by implication, CNAME considered a bad sign (there, and earlier on page 16, second
  "bullet" of the second set of items on page 16),

- the thought that DKIM did NOT chose to use TXT records partially because it was
  infeasible at the time to get an RR type while as the DKIM syntax and semantics
  was still crystallising (or that they had been through enough pain by that point :)

Send-n as currently written may be in the sights, but it is perfectly possible to design
a "number length" DNS tree that will be very heavily cached and uses the DNS ability
to scale and be information-dense (unlike almost any other protocol, even TLS -- ha!).
Whether that would use NAPTRs or just plain TXT records (like everyone else) is an
entirely different question. It would avoid any need for standardisation in the IETF,
which may be the point.

Finally, I really would like to find the bogey man who thought of putting ringtones
in the DNS; I hear much talk of how bad this is, but no-one ever proposed doing such
a perverse thing, AFAICT.

all the best,
  Lawrence

Protocol Action: 'IANA Registration of Enumservices: Guide, Template and IANA Considerations' to Proposed Standard

The IESG has approved the following document:

- 'IANA Registration of Enumservices: Guide, Template and IANA 
   Considerations '
   <draft-ietf-enum-enumservices-guide-22.txt> as a Proposed Standard

This document is the product of the Telephone Number Mapping Working Group. 

The IESG contact persons are Gonzalo Camarillo and Robert Sparks.

A URL of this Internet-Draft is:
http://www.ietf.org/internet-drafts/draft-ietf-enum-enumservices-guide-22.txt

1 - Technical Summary

E.164 Number Mapping (ENUM) provides an identifier mapping mechanism to
map E.164 numbers to Uniform Resource Identifiers.  This document updates
RFC 3761 as part of a suite of including rfc3761bis and a transition
mechanism for the existing IANA registry.  

One of the primary concepts of ENUM is the definition of "Enumservices",
which allows for providing different URIs for different applications of
said mapping mechanism.

This document specifies a revision of the IANA Registry for  
Enumservices, which was originally described in [RFC 3761]. The new
registration processes have been specifically designed to be decoupled
from the existence of the ENUM working group.  

2 - Working Group Summary

Was there anything in the discussion in the interested community that is
worth noting? For example, was there controversy about particular points
or were there decisions where the consensus was particularly rough? Was
the document considered in any WG, and if so, why was it not adopted as a
work item there? 

There was extensive discussion on the alternatives for various processes
involved in the Enumservices registration including what would constitute
Expert Review in this context. The goal was to have a formal process in
place to enable the closure of the ENUM WG.

3 - Document Quality

Are there existing implementations of the protocol? Have a       
significant number of vendors indicated their plan to implement        the
specification? Are there any reviewers that merit special        mention
as having done a thorough review, e.g., one that resulted in important
changes or a conclusion that the document had no substantive issues? If
there was a MIB Doctor, Media Type or other expert review, what was its
course (briefly)? In the case of a Media Type review, on what date was the
request posted?    

Rfc 3761 is globally deployed in multiple contexts and the existing
Enumservice registry has received extensive use.  This new procedure
should simplify the process considerably.

excessive data in the DNS

Jon, I simply don't know what you mean here. Please define  
"excessive", preferably with objective qualitative and quantitative  
metrics. There are plenty of examples of stupid and/or pointless data  
in the DNS. [My favourite was a text-based adventure game.] But who  
gets to decide what's stupid and pointless? Or if those things are  
excessive?

We may well agree that ringtones in the DNS are a possibly apocryphal  
example of "excessive" data. However the people who put that data  
there and those who consume those ringtones would presumably disagree  
with that view. And they'd be right. If whatever they're doing to the  
DNS works for them and isn't harming others, who are we to judge? For  
some definition of we...
