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.  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

RFC 990                                                    November 1986
Assigned Numbers


   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
   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

                          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.

Network Numbers


                        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

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

                             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

                             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.

      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

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

                             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 010.003.000.052, or
   10.3.0.52.

   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 should not
   be listed in the working tables of either the ARPA-Internet or
   DDN-Internet hosts or gateways.

Network Numbers


   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.

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

            For example, the address 0.0.0.37 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 128.9.255.255 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.

Port Numbers


                         ASSIGNED PORT NUMBERS

   Ports are used in the TCP [46,102] 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 [46,100].

   To the extent possible, these same port assignments are used with the
   ISO-TP4 [64].

   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.

Autonomous System Numbers


                   ASSIGNED AUTONOMOUS SYSTEM NUMBERS

   The Exterior Gateway Protocol (EGP) [115,118] 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.

   Autonomous System Numbers:

ARPANET Logical Addresses


                   ASSIGNED ARPANET LOGICAL ADDRESSES

   The ARPANET facility for "logical addressing" is described in
   RFC 878 [74].  A portion of the possible logical addresses are
   reserved for standard uses.

   There are 49,152 possible logical host addresses.  Of these, 256 are
   reserved for assignment to well-known functions.  Assignments for
   well-known functions are made by Joyce Reynolds.  Assignments for
   other logical host addresses are made by the NIC.

ARPANET Link Numbers


                     ASSIGNED ARPANET LINK NUMBERS

   The word "link" here refers to a field in the original ARPANET
   Host/IMP interface leader.  The link was originally defined as an
   8-bit field.  Later specifications defined this field as the
   "message-id" with a length of 12 bits.  The name link now refers to
   the high order 8 bits of this 12-bit message-id field.  The Host/IMP
   interface is defined in BBN Report 1822 [10].

   The low-order 4 bits of the message-id field are called the sub-link.
   Unless explicitly specified otherwise for a particular protocol,
   there is no sender to receiver significance to the sub-link.  The
   sender may use the sub-link in any way he chooses (it is returned in
   the RFNM by the destination IMP), the receiver should ignore the
   sub-link.

IEEE 802 Numbers


                      IEEE 802 NUMBERS OF INTEREST

   Some of the networks of all classes are IEEE 802 Networks.  These
   systems may use a Link Service Access Point (LSAP) field in much the
   same way the ARPANET uses the "link" field, further, there is a
   extension of the LSAP header called the Sub-Network Access Protocol
   (SNAP).

   The IEEE likes to describe numbers in binary in bit transmission
   order, which is the opposite of the big-endian order used throughout
   the Internet protocol documentation.

   At an ad hoc special session on "IEEE 802 Networks and ARP" held
   during the TCP Vendors Workshop (August 1986), an approach to a
   consistent way to sent DOD-IP datagrams and other IP related
   protocols on 802 networks was developed.

   Due to some evolution of the IEEE 802.2 standards and the need to
   provide for a standard way to do additional DOD-IP related protocols
   (such as Address Resolution Protocol (ARP)) on IEEE 802 networks, the
   following new policy is established, which will replace the old
   policy (see RFC-960 and RFC-948 [138]).

   The new policy is for DDN and ARPA-Internet community to use IEEE
   802.2 encapsulation on 802.3, 802.4, and 802.5 networks by using the

   SNAP with an organization code indicating that the following 16 bits
   specify the Ethertype code (where IP = 2048 (0800 hex), see Ethernet
   Numbers of Interest).

                                                                  Header

      |protocol id or org code =K2|    Ether Type   |         802.2 SNAP
      +--------+--------+---------+--------+--------+

   The values of K1 and K2 must be assigned by the IEEE.  There is
   already assigned a value of K1 that indicates that the 5-octet SNAP
   header follows.  There may be a value of K2 that is already assigned
   that indicates that the last two octets of the SNAP header holds the
   EtherType.

   The total length of the SAP Header and the SNAP header is 8-octets,
   making the 802.2 protocol overhead come out on a nice octet boundary.

   K1 is 170.  The IEEE like to talk about things in bit transmission
   order and specifies this value as 01010101.  In big-endian order, as
   used in Internet specifications, this becomes 10101010 binary, or
   AA hex, or 170 decimal.

   We believe that K2 is 0 (zero).  This must be further investigated.
   As an interim measure use K2 = 0.

   The use of the IP LSAP (K1 = 6) is to be phased out as quickly as
   possible.

RFC 990                                                    November 1986
Appendix A


      Within the Research community, network identifiers will only be
      granted to applicants who show evidence that they are acquiring
      standard Bolt Beranek and Newman gateway software or have
      implemented or are acquiring a gateway meeting the Exterior
      Gateway Protocol requirements.  Acquisition of the Berkeley BSD
      4.3 UNIX software might be considered evidence of the latter.

      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.

   Protocol Identifiers

      These assignments are shared by the four communities.

   Port Numbers

      These assignments are shared by the four communities.

   ARPANET Link Numbers

      These assignments are shared by the four communities.

   IP Version Numbers

      These assignments are shared by the four communities.

   TCP, IP and Telnet Option Identifiers

      These assignments are shared by the four communities.

   Implementation:

      Joyce Reynolds is the coordinator for all number assignments.
