RFC 2900                   Internet Standards                August 2001


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 July 17, 2001 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 the IETF process or are submitted individually via
   electronic mail.  Further information about the RFC series is
   contained in section 2.1, RFC 2026 and at http://www.rfc-editor.org.

   This memo is published by the RFC Editor for the IESG and IAB 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 - 3.6 of this
   memo contain the lists of protocols in each stage of standardization
   - Standard, Draft Standard, Proposed Standard, Experimental,
   Historic, 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 RFCs are not included.
   This memo lists the current standards track, Best Current Practice,
   Experimental, and Historic protocols; it is not a complete index to
   RFCs.

   At this URL, a user can:

   (a) Obtain the current "Internet Official Protocol Standards" list.
       See:

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

       This hyper-linked listing is updated daily.

   (b) Retrieve the latest version of this STD 1 memo.  See:

         http://www.rfc-editor.org/go.html, and select STD and "1".

   (c) Retrieve text of any RFC.  See:

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

   (d) Search for RFCs by category.  See:

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

   (e) Search the RFC index for document number, author, title, and/or
       keywords, and retrieve the text of any matching documents.  See:

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

   RFC information can also be retrieved using FTP or email.

2.3 Retrieval using FTP

   RFC-related files may be copied via FTP from the FTP.RFC-EDITOR.ORG
   computer using the FTP username "anonymous" and password
   "[e-mail]".  An FTP user can:

   (a) Retrieve the latest version of this STD 1 memo.

         File: "in-notes/std/std1.txt"

   (b) Retrieve text of any RFC.

       File: "in-notes/rfcnnnn.txt" will retrieve the ASCII version.
       Some RFCs also have secondary Postscript and/or PDF versions,
       available from File: "in-notes/rfcnnnn.ps" and/or
       "in-notes/rfcnnnn.pdf", respectively.

       Here "nnnn" is a 1-4 digit RFC number, with no leading zeros.

2.4 Search and Retrieval Using Email

   To use the RFC Editor's email-based RFC-INFO service, send a request
   to:

      [e-mail]

   In the message body, include your information request.  For example,
   the following message bodies may be used.

   (a) To retrieve the latest version of this STD 1 memo:

         Retrieve: STD
            Doc-ID: STD0001

   (b) To retrieve ASCII text of any RFC:

         Retrieve: RFC
            Doc-ID: RFCnnnn

       Here "nnnn" must be filled with leading zeros to 4 digits.

   (c) The [e-mail] server provides other capabilities,
       e.g., search and retrieval based on author, title, and/or
       keyword.  For more information, send the following message body
       to the server:

         help: help

   The server will email back the results.
