1.3.  Request for Comments Editor (RFC Editor) Contact

   See: www.rfc-editor.org

   The RFC Editor publishes 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.

   How to obtain the most recent edition of this "Internet Official
   Protocol Standards" memo:

      The file "in-notes/std/std1.txt" may be copied via FTP from the
      FTP.ISI.EDU computer using the FTP username "anonymous" and FTP
      password "guest".

1.4.  Requests for Comments Distribution Contact

   RFCs can be obtained via FTP from FTP.ISI.EDU, with the pathname in-
   notes/rfcnnnn.txt (where "nnnn" refers to the number of the RFC).
   Login with FTP username "anonymous" and password "name@host.domain".

   RFCs can also be obtained via electronic mail from ISI.EDU by using
   the RFC-INFO service.  Address the request to "rfc-info@isi.edu" with
   a message body of:

           Retrieve: RFC
              Doc-ID: RFCnnnn

   (Where "nnnn" refers to the number of the RFC (always use 4 digits -
   the DOC-ID of RFC 822 is "RFC0822")).  The RFC-INFO@ISI.EDU server
   provides other ways of selecting RFCs based on keywords and such; for
   more information send a message to "rfc-info@isi.edu" with the
   message body "help: help".

   contact: RFC-Manager@ISI.EDU

1.5.  Sources for Requests for Comments

   Details on many sources of RFCs via FTP or EMAIL may be obtained by
   sending an EMAIL message to "rfc-info@ISI.EDU" with the message body
   "help: ways_to_get_rfcs".  For example:

           To: rfc-info@ISI.EDU
           Subject: getting rfcs

           help: ways_to_get_rfcs
