Status of This Memo

   This memo provides information for the Internet community.  It does
   not specify an Internet standard of any kind.  Distribution of this
   memo is unlimited.

IESG Note

   This document obsoletes RFC 3700.  It also reclassifies RFCs that
   were previously published as STD 1 as Historic.  More specifically,
   this RFC moves RFCs 3000, 3300, 3600, and 3700 to Historic status.

Abstract

   This document is published by the RFC Editor to provide a summary of
   the current standards protocols (as of 18 February 2008).  It lists
   those official protocol standards, Best Current Practice, and
   Experimental RFCs that have not been obsoleted; it is not a complete
   index to the RFC series.  Newly published RFCs and RFCs whose status
   has changed are starred.

   For an up-to-date list, see http://www.rfc-editor.org/rfcxx00.html,
   which is updated daily.

RFC 5000          Internet Official Protocol Standards          May 2008


1.  Overview

   This memo contains a snapshot of the state of standardization of
   protocols used in the Internet, as determined by the Internet
   Engineering Task Force (IETF).  It is a 18 February 2008 snapshot of
   the current official protocol standards list and the Best Current
   Practice list, which is updated daily and is available from the RFC
   Editor Web site.

   The RFC Editor publishes Request for Comments (RFC) documents that
   are the output of 4 streams: IAB, IETF, IRTF, and Independent
   Submission via the RFC Editor.

   This memo is published by the RFC Editor for the IESG and IAB, in
   which the categorizations are in accordance with Section 2.1 of "The
   Internet Standards Process -- Revision 3", RFC 2026, which specifies
   the rules and procedures by which all Internet standards are set.
   Sections 3.1 - 3.7 of this memo contain the lists of protocols in
   each stage of standardization - Standard, Draft Standard, Proposed
   Standard, Experimental, as well as Best Current Practice documents.
   Protocols that are new to this document or have been moved from one
   protocol level to another, or that differ from the previous edition
   of this document are marked with an asterisk.  Informational and
   Historic RFCs are not included.  This list is not a complete index to
   RFCs.

2.  RFC Resources and Retrieval

   This list is a live document that is updated daily on the RFC Editor
   site at:

      http://www.rfc-editor.org/rfcxx00.html

   RFCs are available online via http and ftp as:

      http://www.rfc-editor.org/rfc/rfcXXXX.txt
      ftp://ftp.rfc-editor.org/in-notes/rfcXXXX.txt

   where XXXX represents the corresponding RFC number.

   The RFC Editor maintains the official repository of all RFCs and
   indexes to them.  The site also provides additional information about
   the history of the RFC Editor, current submission and review
   procedures, and editorial and publication procedures.  Please see the
   RFC Editor site for all other RFC related information:
