The advent of IPv6 in addition to IPv4 makes hosts and servers dual-
stack. SIP communications can be used in both environments but there
is little understanding what will happen if some nodes are dual-stack
while others, presently the majority, is IPv4 only enabled. This
document describes some scenarios and associated issues when dual-
stack users and servers try to communicate with IPv4 only hosts using
SIP. It is not evident that interoperability is achieved, and if that
is not the case, this would severely limit the usability of both SIP
and IPv6.

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
