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.
