The IPv6 Addressing Architecture [Hinden, 1998] defines the 'IPv4-mapped
IPv6 address.' This representation is used in the IPv6 basic API
[Gilligan, 1999] to denote IPv4 addresses using AF_INET6 sockets. The
use of IPv4-mapped addresses on AF_INET6 sockets degrades portability,
complicates IPv6 systems, and is likely to create security problems.
This document discusses each issue in turn. Finally, it proposes to
resolve these problems by recommending deprecation of this mechanism.

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.
