A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : ENUM Requirement for EDNS0 Support
Author(s) : L. Conroy, J. Reid
Filename : draft-conroy-enum-edns0-02.txt
Pages : 16
Date : 2006-6-29
Support for EDNS0 (Extension Mechanisms for DNS) is mandated in this
document for DNS entities querying for or serving NAPTR records. In
general those entities will be supporting ENUM resolution. This
requirement is needed because DNS responses to ENUM-related queries
generally return large RRSets. Without EDNS0 support these lookups
would result in truncated responses and repeated queries over TCP
transport. That has a severe impact on DNS server load and on the
latency of those queries.
This document updates RFC3761 only in adding this requirement.

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.
