A New Internet-Draft is available from the on-line Internet-Drafts directories.


	Title		: The DISCOVER opcode
	Author(s)	: B. Manning, P. Vixie, E. Guttman

The QUERY opcode in the DNS is designed for unicast. With the 
development of multicast capabilities in the DNS, it is desireable
to have a more robust opcode for server interactions since a single
request may result in replies from multiple responders. So DISCOVER
is defined to deal with replies from multiple responders.
As such, this document extend the core DNS specifications to allow
clients to have a method for coping with replies from multiple
responders. Use of this new opcode may facilitate DNS operations in
modern networking topologies.

Send a message to:

In the body type:
	"FILE /internet-drafts/draft-ymbk-opcode-discover-02.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.
