Status of this Memo

   This memo is an official status report on the numbers used in
   protocols in the Internet community.  Distribution of this memo is
   unlimited.

Introduction

   This Network Working Group Request for Comments documents the
   currently assigned values from several series of numbers used in
   network protocol implementations.  This RFC will be updated
   periodically, and in any case current information can be obtained
   from Joyce Reynolds.  If you are developing a protocol or application
   that will require the use of a link, socket, port, protocol, etc.,
   please contact Joyce to receive a number assignment.

   Most of the protocols mentioned here are documented in the RFC series
   of notes.  Some of the items listed are undocumented.  Further
   information on protocols can be found in the memo "Official Internet
   Protocols" [91].  The more prominent and more generally used are
   documented in the "DDN Protocol Handbook, Volume Two, DARPA Internet
   Protocols" [36] prepared by the NIC.  Other collections of older or
   obsolete protocols are contained in the "Internet Protocol Transition
   Workbook" [57], or in the "ARPANET Protocol Transition Handbook"
   [38].  For further information on ordering the complete 1985 DDN
   Protocol Handbook, write: SRI International (SRI-NIC), DDN Network

RFC 1010 - Assigned Numbers                                     May 1987


   right hand margin of the page indicates a reference for the listed
   protocol, where the number ("nn") cites the document and the letters
   ("iii") cites the person.  Whenever possible, the letters are a NIC
   Ident as used in the WhoIs (NICNAME) service.

   The convention in the documentation of Internet Protocols is to
   express numbers in decimal and to picture data in "big-endian" order
   [14].  That is, fields are described left to right, with the most
   significant octet on the left and the least significant octet on the
   right.

   The order of transmission of the header and data described in this
   document is resolved to the octet level.  Whenever a diagram shows a
   group of octets, the order of transmission of those octets is the
   normal order in which they are read in English.  For example, in the
   following diagram the octets are transmitted in the order they are
   numbered.

                                    
    0                   1                   2                   3   
    0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

                      Transmission Order of Bytes

   Whenever an octet represents a numeric quantity the left most bit in
   the diagram is the high order or most significant bit.  That is, the
   bit labeled 0 is the most significant bit.  For example, the
   following diagram represents the value 170 (decimal).

                                    
                            0 1 2 3 4 5 6 7 
                           +-+-+-+-+-+-+-+-+
                           |1 0 1 0 1 0 1 0|
                           +-+-+-+-+-+-+-+-+

                          Significance of Bits

   Similarly, whenever a multi-octet field represents a numeric quantity
   the left most bit of the whole field is the most significant bit.
   When a multi-octet quantity is transmitted the most significant octet
   is transmitted first.

RFC 1010 - Assigned Numbers                                     May 1987
Port Numbers


                              PORT NUMBERS

   Ports are used in the TCP [36,81] to name the ends of logical
   connections which carry long term conversations.  For the purpose of
   providing services to unknown callers, a service contact port is
   defined.  This list specifies the port used by the server process as
   its contact port.  The contact port is sometimes called the
   "well-known port".

   To the extent possible, these same port assignments are used with the
   UDP [37,79].

   To the extent possible, these same port assignments are used with the
   ISO-TP4 [52].

   The assigned ports use a small portion of the possible port numbers.
   The assigned ports have all except the low order eight bits cleared
   to zero.  The low order eight bits are specified here.

   Port Assignments:
