A Revised Internet-Draft is available from the on-line Internet-Drafts 
directories. This draft is a work item of the IPNG Working Group of the 
IETF.

In order to implement the version 6 Internet Protocol (IPv6) [1] in an 
operating system based on Berkeley Unix (4.x BSD), changes must be made to 
the application program interface (API).  TCP/IP applications written for 
BSD-based operating systems have in the past enjoyed a high degree of 
portability because most of the systems derived from BSD provide the same 
API, known informally as "the socket interface".  We would like the same 
portability with IPv6.  This memo presents a set of extensions to the BSD 
socket API to support IPv6.  The changes include a new data structure to 
carry IPv6 addresses, new name to address translation library functions, 
new address conversion functions, and some new setsockopt() options.  The 
extensions are designed to provide access to IPv6 features, while 
introducing a minimum of change into the system and providing complete 
compatibility for existing IPv4 applications.

Send a message to:  [e-mail]. In the body type: 
     "FILE /internet-drafts/draft-ietf-ipngwg-bsd-api-03.txt".
							
NOTE: The mail server at ds.internic.net 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.
							
For questions, please mail to [e-mail].
							

Below is the data which will enable a MIME compliant mail reader 
implementation to automatically retrieve the ASCII version
of the Internet-Draft.
