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           : DNS Referral Response Size Issues
	Author(s)       : P. Vixie, A. Kato

With a mandated default minimum maximum UDP message size of 512
octets, the DNS protocol presents some special problems for zones
wishing to expose a moderate or high number of authority servers (NS
RRs).  This document explains the operational issues caused by, or
related to this response size limit, and suggests ways to optimize
the use of this limited space.  Guidance is offered to DNS server
implementors and to DNS zone operators.

In the body type:

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.
