Internet Numbers                                                 RFC 997

   The convention in the documentation of Internet Protocols is to
   express numbers in decimal and to picture data in "big-endian" order
   [31].  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
   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.

Internet Numbers                                                 RFC 997
Network Numbers

                             NETWORK NUMBERS

   The network numbers listed here are used as internet addresses by the
   Internet Protocol (IP) [11,21].  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 4 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

Network Numbers

      The fourth type of address, class D, is used as a multicast
      address [10].  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 VENERA.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
   research Internet and operational 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 number.

   The administrators of independent networks must apply separately for
   permission to interconnect their network with the Internet.
   Independent networks should not be listed in the working tables of
   the Internet hosts or gateways.

   For various reasons, the assigned numbers of networks are sometimes
   changed.  To ease the transition the old number will be listed for a

Network Numbers

   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.

                       AUTONOMOUS SYSTEM NUMBERS

   The Exterior Gateway Protocol (EGP) [25,27] specifies that groups of
   gateways may form autonomous systems.  The EGP provides a 16-bit
   field for identifying such systems.  The values of this field are
   registered here.

Appendix A

                               APPENDIX A

   The network numbers in class A, B, and C network addresses are
   allocated among Research, Defense, Government (Non-Defense) and
   Commercial uses.

   Class A (highest-order bit 0)

      Research allocation:             8
      Defense allocation:             24
      Government allocation:          24
      Commercial allocation:          94
      Reserved Addresses:   (0, 127)
      Total                          128

   Class B (highest-order bits 1-0)

      Research allocation:          1024
      Defense allocation:           3072
      Government allocation:        3072
      Commercial allocation:       12286
      Reserved Addresses: (0, 16383)
      Total                        16384

   Class C (highest-order bits 1-1-0)

      Research allocation:           65536
      Defense allocation:           458725
      Government allocation:        458725
      Commercial allocation:       1572862
      Reserved Addresses: (0, 2097151)
      Total                        2097152

   Class D (highest-order bits 1-1-1-0)

      All addresses in this class are allocated for multicast use.

   Class E (highest-order bits 1-1-1-1)

      All addresses in this class are reserved for future use.

Appendix A

   Experimental networks which later become operational need not be
   renumbered.  Rather, the identifiers could be moved from Research to
   Defense, Government or Commercial status.  Thus, network identifiers
   may change state among Research, Defense, Government and Commercial,
   but the number of identifiers allocated to each use must remain
   within the limits indicated above.  To make possible this fluid
   assignment, the network identifier spaces are not allocated by simple
   partition, but rather by specific assignment.

   Also, organizations not currently affiliated with the Internet may be
   assigned numbers for networks for non-connected service.  If at some
   later time such networks are connecteed to the Internet (with
   appropriate prermissions and approvals) the networks need not be
