FYI. [note that the announcement didn't pick up the new draft title--it's
no longer limited to qtype=addr]

This version resolves the issues which were raised wrt coexistence of
data/nodata in qtype=addr answers, adds rules for A+AAAA in the additional
data section of other messages, introduces rules for managing truncated
response messages, and incorporates some cleaning.

I'm still not advocating this as a WG work-item, at least not yet anyway.
However, in the absence of documentation for other approaches with the
same level of data- and behavioral-consistency, it seems that this is the
direction we should go when this subject comes up again.

A New Internet-Draft is available from the on-line Internet-Drafts directories.


	Title		: The ADDR DNS Query-Type
	Author(s)	: E. Hall
	Filename	: draft-hall-qtype-addr-01.txt
	Pages		: 13
	Date		: 2003-11-26
	
This document defines mechanisms for providing all IP address 
resource records (specifically including any A and AAAA resource 
records) in DNS response messages. Specifically, this document 
defines an 'ADDR' query-type which allows a system to issue a 
single lookup for all of the addressing resource records 
associated with a domain name (explicitly including any IPv4 and 
IPv6 resource records), and also defines an algorithm for DNS 
servers to use when returning supplemental address data in the 
additional-data section of a response message.

A URL for this Internet-Draft is:
http://www.ietf.org/internet-drafts/draft-hall-qtype-addr-01.txt

To remove yourself from the IETF Announcement list, send a message to 
ietf-announce-request with the word unsubscribe in the body of the message.

Internet-Drafts are also available by anonymous FTP. Login with the username
"anonymous" and a password of your e-mail address. After logging in,
type "cd internet-drafts" and then
	"get draft-hall-qtype-addr-01.txt".

A list of Internet-Drafts directories can be found in
http://www.ietf.org/shadow.html 
or ftp://ftp.ietf.org/ietf/1shadow-sites.txt


Internet-Drafts can also be obtained by e-mail.

Send a message to:
	mailserv@ietf.org.
In the body type:
	"FILE /internet-drafts/draft-hall-qtype-addr-01.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
