                            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.

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.  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.  The more prominent and more generally used are documented
   in the "Internet Protocol Transition Workbook" [35] or in the old
   "ARPANET Protocol Handbook" [36] prepared by the NIC.  Some of the
   items listed are undocumented.  Further information on protocols can
   be found in the memo "Official ARPA-Internet Protocols" [92].

   In all cases the name and mailbox of the responsible individual is
   indicated.  In the lists that follow, a 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, letters
   are a NIC Ident as used in the WHOIS service.

Network Numbers


                        ASSIGNED NETWORK NUMBERS

   The network numbers listed here are used as internet addresses by the
   Internet Protocol (IP) [35,80].  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

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

                             Class C Address

      Note:  No addresses are allowed with the three highest-order bits
      set to 1-1-1.  These addresses (sometimes called "class D") are
      reserved.




Reynolds & Postel                                               [Page 2]



Assigned Numbers                                                 RFC 943
Network Numbers


   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 USC-ISIF.ARPA in dotted decimal is 010.002.000.052, or
   10.2.0.52.

   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
   identification).

   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
   number.

   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 need not be
   listed in the working tables of either the ARPA-Internet or
   DDN-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
   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
      hosts.  When such usage is called for, the address zero is to be
      interpreted as meaning "this", as in "this network".  The address
      of all ones are to be interpreted as meaning "all", as in "all
      hosts".  For example, the address 128.9.255.255 could be



Reynolds & Postel                                               [Page 3]



Assigned Numbers                                                 RFC 943
Network Numbers


      interpreted as meaning all hosts on the network 128.9.  Or, the
      address 0.0.0.37 could be interpreted as meaning host 37 on this
      network.

   Ports are used in the TCP [35,81] 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 [35,79].

   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.
