3) Integration 

  Definition of a SIP address record (AA) for DNS. Draft available from
  INRIA.

  Developed a simple technique to support the FTP PORT command in 2-party
  and some 3-party FTP transactions without any change to the protocol.
  The PORT command is used by the FTP client to pass a 32 bit IPv4 address
  for the server to use in making the data connection. The FTP server
  generates the SIP destination address for the data connection by
  concatenating the high-order 32 bits of the client's SIP address with the
  32 bit IPv4 address passed in FTP's PORT command.

  In the Sun prototype, implemented full binary compatibility for exiting
  IPv4 applications.  Existing IPv4 applications that passively accept TCP
  connections or receive UDP datagrams can accept connections or datagrams
  that arrive via any of the three internet datagram formats: IPv4, IPAE or
  SIP.  Existing IPv4 applications that transmit UDP datagrams or actively
  open TCP connections will generate traffic that uses the IPv4 form only.

4) Work in Progress

  Proposal for address resolution and discovery loosely based on ES-IS and
  ARP has been developed and is being discussed.

  A proposal for a new ICMP "Destination has Moved" message is being
  designed to deal with mobile hosts and for domains that change their
  address prefix.

  A study is available from Ran Atkinson on integration of SP3 over SIP.
  Work is underway to produce specification.

  A rough draft of a SIP Sensitivity Label Option has been distributed to
  the mailing list.  It is titled "SIPSO, A Generic SIP Sensitivity
  Labeling Option".
