Support for IPv6 in Session Description Protocol (SDP)



Alternative Format: Original Text Document



RFC 3266    Support for IPv6 in Session Description Protocol   June 2002


      hexseq  =             hex4 *( ":" hex4)

      hex4    =             1*4HEXDIG

4. Example SDP description with IPv6 addresses

   The following is an example SDP description using the above ABNF for
   IPv6 addresses.  In particular, the origin and connection fields
   contain IPv6 addresses.

      v=0
      o=nasa1 971731711378798081 0 IN IP6 2201:056D::112E:144A:1E24
      s=(Almost) live video feed from Mars-II satellite
      p=+1 713 555 1234
      c=IN IP6 FF1E:03AD::7F2E:172A:1E24
      t=3338481189 3370017201
      m=audio 6000 RTP/AVP 2
      a=rtpmap:2 G726-32/8000
      m=video 6024 RTP/AVP 107
      a=rtpmap:107 H263-1998/90000

5. Note for implementors

   An implementation may receive an SDP session description with an IPv6
   address whose format [1] is internally that of an IPv4 mapped
   address.  Note that such an address is actually the address of an
   IPv4-only node, and implementors are warned to interpret IPv4 mapped
   addresses as equivalent to IP4.

6. IANA Considerations

   This document updates the definition of the IP6 addrtype parameter
   found in RFC 2327.

7. Security Considerations

   No additional considerations above what is stated in section 7 of RFC
   2327.
