                            ASSIGNED NUMBERS

Status of this Memo

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


   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.  The assignment of numbers is also handled by
   Joyce.  If you are developing a protocol or application that will
   require the use of a link, socket, port, protocol, network number,
   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
   ARPA-Internet Protocols" [114].  The more prominent and more
   generally used are documented in the "DDN Protocol Handbook" [46]
   prepared by the NIC.  Other collections of older or obsolete
   protocols are contained in the "Internet Protocol Transition Workbook
   [47], or in the "ARPANET Protocol Handbook" [48].  For further
   information on ordering the complete 1985 DDN Protocol Handbook,

   In the entries below the name and mailbox of the responsible
   individual is indicated.  The bracketed entry, e.g., [nn,iii], at the
   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
   [131].  That is, fields are described left to right, with the most
   significant octet on the left and the least significant octet on the

   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

    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 
   |       1       |       2       |       3       |       4       |
   |       5       |       6       |       7       |       8       |
   |       9       |      10       |      11       |      12       |

                      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
ToP   noToC   RFC0990 - Page 3
   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.

                        ASSIGNED NETWORK NUMBERS

   The network numbers listed here are used as internet addresses by the
   Internet Protocol (IP) [46,101].  The IP uses a 32-bit address field
   and divides that address into a network part and a "rest" or local
   address part.  The division takes 3 forms or classes.

      The first type of address, or class A, has a 7-bit network number
      and a 24-bit local address.  The highest-order bit is set to 0.
      This allows 128 class A networks.

                           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 
      |0|   NETWORK   |                Local Address                  |

                             Class A Address

      The second type of address, class B, has a 14-bit network number
      and a 16-bit local address.  The two highest-order bits are set to
      1-0.  This allows 16,384 class B networks.

                           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 
      |1 0|           NETWORK         |          Local Address        |

                             Class B Address

      The third type of address, class C, has a 21-bit network number
      and a 8-bit local address.  The three highest-order bits are set
      to 1-1-0.  This allows 2,097,152 class C networks.

                           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 
      |1 1 0|                    NETWORK              | Local Address |

                             Class C Address
ToP   noToC   RFC0990 - Page 5
      The fourth type of address, class D, is used as a multicast
      address [44].  The four highest-order bits are set to 1-1-1-0.

                           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 
      |1 1 1 0|                  multicast address                    |

                             Class D Address

      Note:  No addresses are allowed with the four highest-order bits
      set to 1-1-1-1.  These addresses, called "class E", are reserved.

   One commonly used notation for internet host addresses divides the
   32-bit address into four 8-bit fields and specifies the value of each
   field as a decimal number with the fields separated by periods.  This
   is called the "dotted decimal" notation.  For example, the internet
   address of B.ISI.EDU in dotted decimal is, or

   The dotted decimal notation will be used in the listing of assigned
   network numbers.  The class A networks will have nnn.rrr.rrr.rrr, the
   class B networks will have nnn.nnn.rrr.rrr, and the class C networks
   will have nnn.nnn.nnn.rrr, where nnn represents part or all of a
   network number and rrr represents part or all of a local address.

   There are four catagories of users of Internet Addresses: Research,
   Defense, Government (Non-Defense), and Commercial.  To reflect the
   allocation of network identifiers among the categories, a
   one-character code is placed to the left of the network number: R for
   Research, D for Defense, G for Government, and C for Commercial (see
   Appendix A for further details on this division of the network

   Network numbers are assigned for networks that are connected to the
   ARPA-Internet and DDN-Internet, and for independent networks that use
   the IP family protocols (these are usually commercial).  These
   independent networks are marked with an asterisk preceding the

   The administrators of independent networks must apply separately for
   permission to interconnect their network with either the
   ARPA-Internet of the DDN-Internet.  Independent networks should not
   be listed in the working tables of either the ARPA-Internet or
   DDN-Internet hosts or gateways.
ToP   noToC   RFC0990 - Page 6
   For various reasons, the assigned numbers of networks are sometimes
   changed.  To ease the transition the old number will be listed for a
   transition period as well.  These "old number" entries will be marked
   with a "T" following the number and preceding the name, and the
   network name will be suffixed "-TEMP".

   Special Addresses:

      In certain contexts, it is useful to have fixed addresses with
      functional significance rather than as identifiers of specific

         The address zero is to be interpreted as meaning "this", as in
         "this network".

            For example, the address could be interpreted as
            meaning host 37 on this network.

         The address of all ones are to be interpreted as meaning "all",
         as in "all hosts".

            For example, the address could be interpreted
            as meaning all hosts on the network 128.9.

         The class A network number 127 is assigned the "loopback"
         function, that is, a datagram sent by a higher level protocol
         to a network 127 address should loop back inside the host.  No
         datagram "sent" to a network 127 address should ever appear on
         any network anywhere.
