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 RFC822 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:
