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.Table of Contents   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.
