Abstract

   This document describes the use of Internet Protocol Version 6 (IPv6)
   addresses in conjunction with the Session Description Protocol (SDP).
   Specifically, this document clarifies existing text in SDP with
   regards to the syntax of IPv6 addresses.

1. Introduction

   SDP is intended for describing multimedia sessions for the purposes
   of session announcement, session invitation, and other forms of
   multimedia session initiation.  It is a text format description that
   provides many details of a multimedia session including: the
   originator of the session, a URL related to the session, the
   connection address for the session media(s), and optional attributes
   for the session media(s).  Each of these pieces of information may
   involve one or more IPv6 addresses.  The ABNF for IP addresses in SDP
   currently leaves the syntax for IPv6 addresses undefined.  This
   document attempts to complete the ABNF to include IPv6 addresses.

   Accordingly, the address type "IP6" indicating an IPv6 address,
   should be allowed in the connection field, "c=", of the SDP.  The
   ABNF already reflects this, though the "Connection Data" text under
   section 6 of RFC 2328 currently only defines the "IP4" address type.
