                    Introduction to the F.Y.I. Notes

Status of this Memo

   This RFC is the first in a new sub-series of RFCs called FYIs (For
   Your Information).  This memo provides information for the Internet
   community.  It does not specify any standard.  Distribution of this
   memo is unlimited.

1.  Introduction

   The FYI series of notes is designed to provide Internet users with a
   central repository of information about any topics which relate to
   the Internet.  FYIs topics may range from historical memos on "Why it
   was was done this way" to answers to commonly asked operational
   questions.

   The FYIs are intended for a wide audience.  Some FYIs will cater to
   beginners, while others will discuss more advanced topics.  An FYI
   may be submitted by anyone who has something to contribute and has
   the time to do so.

2.  Why RFCs

   There are several reasons why the FYIs are part of the larger RFC
   series of notes.  The formost reason is that the distribution
   mechanisms for RFCs are tried and true.  Anyone who can get an RFC,
   can automatically get an FYI.  More importantly, anyone who knows of
   the RFC series, can easily find out about the FYIs.

   Another reason for making FYIs part of the RFC series is that the
   maintainance mechanisms for RFCs are already in place and funded.  It
   makes sense to maintain similar documents is a similar way.  After
   all, there have been informational RFCs before.

   Finally, the name RFC has come to carry a meaning with it.  There is
   credibility associated memos carrying the RFC label.  FYIs should
   share that respect.

3.  Format Rules

   Since the FYIs are a part of the RFC series, they must conform to
   RFC-1111 (Request for Comments on Request for Comments: Instructions
   to RFC Authors) with respect to format.  Ideally, they should be
   submitted in ASCII format, as described by section 2a, of RFC-1111.

4.  Status Statement

   Each RFC must include on its first page the "Status of this Memo"
   section which contains a paragraph describing the intention of the
   RFC.  This section is meant to convey the status granted by the RFC
   Editor and the Internet Activities Board (IAB).  There are several
   reasons for publishing a memo as an RFC, for example, to make
   available some information for interested people, or to begin or
   continue a discussion of an interesting idea, or to make available
   the specification of a protocol.

   For example:

   This RFC is the first in a new sub-series of RFCs called FYIs (For
   Your Information).  This memo provides information for the Internet
   community.  It does not specify any standard.  Distribution of this
   memo is unlimited.

5.  Distribution Statement

   Each FYI is to also include a "distribution statement".  As the
   purpose of the FYI series is to disseminate information, there is no
   reason for the distribution to be anything other than "unlimited".

   Typically, the distribution statement will simply be the sentence
   "Distribution of this memo is unlimited." appended to the "Status of
   this Memo" section.

6. Security Considerations

   All FYIs must contain a section that discusses the security
   considerations of the procedures that are the main topic of the RFC.

7.  Author's Address

   Each FYI must have at the very end a section giving the author's
   address, including the name and postal address, the telephone number,
   and the Internet email address.

8.  Relation to other FYIs

   Sometimes an FYI adds information on a topic discussed in a previous
   FYI or completely replaces an earlier FYI.  There are two terms used
   for these cases respectively, UPDATES and OBSOLETES.  A document that
   obsoletes an earlier document can stand on its own.  A document that
   merely updates an earlier document cannot stand on its own; it is
   something that must be added to or inserted into the existing
   document, and has limited usefulness independently.

   UPDATES

      To be used as a reference from a new item that cannot be used
      alone (i.e., one that supplements a previous document), to refer
      to the previous document.  The newer publication is a part that
      will supplement or be added on to the existing document; e.g., an
