Title : Modified Network Address Translation - Protocol Translation

Filename : draft-van-beijnum-v6ops-mnat-pt-00.txt

A smooth transition from IPv4 to IPv6 requires that either all hosts
are upgraded to dual stack before the first hosts can become IPv6-
only, or that there be some mechanism for IPv6-only hosts to talk to
IPv4-only hosts. Expecting the former within a reasonable timeframe
isn't realistic, based on current adoption of dual stack combined
with the latest projections for the IPv4 depletion that point to a
date early in the next decade. And the IETF has recently deprecated
the main mechanism that allows the latter: NAT-PT.
This document proposes a modified form of NAT-PT that addresses the
reasons why the mechanism was deprecated and currently understood
requirements. This should allow future deployment of the modified
NAT-PT as an IPv4-to-IPv6 transition mechanism, giving operators the
option of running their networks largely IPv6-only.

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.
