    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
       the Internet Assigned Numbers Authority (IANA).  If you are developing
       a protocol or application that will require the use of a link, socket,
       port, protocol, etc., please contact the IANA 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 "IAB Official
       Protocol Standards" [62].

       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.

    Data Notations

       The convention in the documentation of Internet Protocols is to
       express numbers in decimal and to picture data in "big-endian" order
       [21].  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
          +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
          |       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.

    Reynolds & Postel                                               [Page 3]

    RFC 1340                    Assigned Numbers                   July 1992

    Special Addresses:

       There are five classes of IP addresses: Class A through Class E
       [119].  Of these, Class E addresses are reserved for experimental
       use.  A gateway which is not participating in these experiments must
       ignore all datagrams with a Class E destination IP address.  ICMP
       Destination Unreachable or ICMP Redirect messages must not result
       from receiving such datagrams.

       There are certain special cases for IP addresses [11].  These special
       cases can be concisely summarized using the earlier notation for an
       IP address:

             IP-address ::=  { <Network-number>, <Host-number> }

                or

             IP-address ::=  { <Network-number>, <Subnet-number>,
                                                             <Host-number> }

       if we also use the notation "-1" to mean the field contains all 1
       bits.  Some common special cases are as follows:

             (a)   {0, 0}

                This host on this network.  Can only be used as a source
                address (see note later).

             (b)   {0, <Host-number>}

                Specified host on this network.  Can only be used as a
                source address.

             (c)   { -1, -1}

                Limited broadcast.  Can only be used as a destination
                address, and a datagram with this address must never be
                forwarded outside the (sub-)net of the source.

             (d)   {<Network-number>, -1}

                Directed broadcast to specified network.  Can only be used
                as a destination address.

             (e)   {<Network-number>, <Subnet-number>, -1}

                Directed broadcast to specified subnet.  Can only be used as
                a destination address.

    RFC 1340                    Assigned Numbers                   July 1992

             (f)   {<Network-number>, -1, -1}

                Directed broadcast to all subnets of specified subnetted
                network.  Can only be used as a destination address.

             (g)   {127, <any>}

                Internal host loopback address.  Should never appear outside
                a host.

                               WELL KNOWN PORT NUMBERS

    The Well Known Ports are controlled and assigned by the IANA and on most
    systems can only be used by system (or root) processes or by programs
    executed by privileged users.

    Ports are used in the TCP [45,106] 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 [46,104].

    The assigned ports use a small portion of the possible port numbers.
    For many years the assigned ports were in the range 0-255.  Recently,
    the range for assigned ports managed by the IANA has been expanded to
    the range 0-1023.

                              REGISTERED PORT NUMBERS

    The Registered Ports are not controlled by the IANA and on most systems
    can be used by ordinary user processes or programs executed by ordinary
    users.

    Ports are used in the TCP [45,106] 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.  While the IANA can not control uses of these ports it
    does register or list uses of these ports as a convienence to the
    community.

    To the extent possible, these same port assignments are used with the
    UDP [46,104].

    The Registered Ports are in the range 1024-65535.

    Port Assignments:

                             IANA ETHERNET ADDRESS BLOCK

       The IANA owns an Ethernet address block which may be used for
       multicast address asignments or other special purposes.

       The address block in IEEE binary is (which is in bit transmission
       order):

                           0000 0000 0000 0000 0111 1010

       In the normal Internet dotted decimal notation this is 0.0.94 since
       the bytes are transmitted higher order first and bits within bytes
       are transmitted lower order first (see "Data Notation" in the
       Introduction).

       IEEE CSMA/CD and Token Bus bit transmission order: 00 00 5E

       The latter representation corresponds to the Internet standard bit-
       order, and is the format that most programmers have to deal with.
       Using this representation, the range of Internet Multicast addresses
       is:

              01-00-5E-00-00-00  to  01-00-5E-7F-FF-FF  in hex, or

              1.0.94.0.0.0  to  1.0.94.127.255.255  in dotted decimal

                                 IP TOS PARAMETERS

       This documents the default Type-of-Service values that are currently
       recommended for the most important Internet protocols.

       There are four assigned TOS values: low delay, high throughput, high
       reliability, and low cost; in each case, the TOS value is used to
       indicate "better".  Only one TOS value or property can be requested
       in any one IP datagram.

       Generally, protocols which are involved in direct interaction with a
       human should select low delay, while data transfers which may involve
       large blocks of data are need high throughput.  Finally, high
       reliability is most important for datagram-based Internet management
       functions.

       Application protocols not included in these tables should be able to
       make appropriate choice of low delay (8 decimal, 1000 binary) or high
       throughput (4 decimail, 0100 binary).

       The following are recommended values for TOS:

                      ----- Type-of-Service Value -----

          Protocol           TOS Value

          TELNET (1)         1000                 (minimize delay)

          FTP
            Control          1000                 (minimize delay)
            Data (2)         0100                 (maximize throughput)

          TFTP               1000                 (minimize delay)

          SMTP (3)
            Command phase    1000                 (minimize delay)
            DATA phase       0100                 (maximize throughput)

          Domain Name Service
            UDP Query        1000                 (minimize delay)
            TCP Query        0000
            Zone Transfer    0100                 (maximize throughput)

          NNTP               0001                 (minimize monetary cost)

    RFC 1340                    Assigned Numbers                   July 1992

          ICMP
            Errors           0000
            Requests         0000 (4)
            Responses        <same as request> (4)

          Any IGP            0010                 (maximize reliability)

          EGP                0000

          SNMP               0010                 (maximize reliability)

          BOOTP              0000

          Notes:

          (1) Includes all interactive user protocols (e.g., rlogin).

          (2) Includes all bulk data transfer protocols (e.g., rcp).

          (3) If the implementation does not support changing the TOS during
          the lifetime of the connection, then the recommended TOS on
          opening the connection is the default TOS (0000).

          (4) Although ICMP request messages are normally sent with the
          default TOS, there are sometimes good reasons why they would be
          sent with some other TOS value.  An ICMP response always uses the
          same TOS value as was used in the corresponding ICMP request
          message.

       An application may (at the request of the user) substitute 0001
       (minimize monetary cost) for any of the above values.

       The Bootstrap Protocol (BOOTP) RFC-951 [36] describes an IP/UDP
       bootstrap protocol (BOOTP) which allows a diskless client machine to
       discover its own IP address, the address of a server host, and the
       name of a file to be loaded into memory and executed.  The BOOTP
       Vendor Information Extensions RFC-1084 [117] describes an addition to
       the Bootstrap Protocol (BOOTP).

       Vendor Extensions are listed below:

                           NETWORK MANAGEMENT PARAMETERS

       For the management of hosts and gateways on the Internet a data
       structure for the information has been defined.  This data structure
       should be used with any of several possible management protocols, such
       as the "Simple Network Management Protocol" (SNMP) RFC-1157 [15], or
       the "Common Management Information Protocol over TCP" (CMOT) [142].

       The data structure is the "Structure and Indentification of Management
       Information for TCP/IP-based Internets" (SMI) RFC-1155 [120], and the
       "Management Information Base for Network Management of TCP/IP-based
       Internets" (MIB-II) [121].

       The SMI includes the provision for panrameters or codes to indicate
       experimental or private data structures.  These parameter assignments
       are listed here.

       The older "Simple Gateway Monitoring Protocol" (SGMP) RFC-1028 [37]
       also defined a data structure.  The parameter assignments used with
       SGMP are included here for hist orical completeness.

       The network management object identifiers are under the iso (1), org
       (3), dod (6), internet (1), or 1.3.6.1, branch of the name space.

                               MILNET LOGICAL ADDRESSES

       The MILNET facility for "logical addressing" is described in RFC-878
       [57] and RFC-1005 [109].  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 the IANA.  Assignments for other
       logical host addresses are made by the NIC.

                                 MILNET LINK NUMBERS

       The word "link" here refers to a field in the original MILNET
       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 [2].

       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.

                             MILNET X.25 ADDRESS MAPPINGS

       All MILNET hosts are assigned addresses by the Defense Data Network
       (DDN).  The address of a MILNET host may be obtained from the Network
       Information Center (NIC), represented as an ASCII text string in what
       is called "host table format".  This section describes the process by
       which MILNET X.25 addresses may be derived from addresses in the NIC
       host table format.

       A NIC host table address consists of the ASCII text string
       representations of four decimal numbers separated by periods,
       corresponding to the four octeted of a thirty-two bit Internet
       address.  The four decimal numbers are referred to in this section as
       "n", "h' "l", and "i".  Thus, a host table address may be represented
       as: "n.h.l.i".  Each of these four numbers will have either one, two,
       or three decimal digits and will never have a value greater than 255.
       For example, in the host table, address: "10.2.0.124", n=10, h=2,
       l=0, and i=124.  To convert a host table address to a MILNET X.25
       address:

          1.  If h < 64, the host table address corresponds to the X.25
          physical address:

                                 ZZZZ F IIIHHZZ (SS)

          where:

               ZZZZ = 0000    as required

               F = 0          because the address is a physical address;

               III            is a three decimal digit respresentation of
                              "i", right-adjusted and padded with leading
                              zeros if required;

               HH             is a two decimal digit representation of "h",
                              right-adjusted and padded with leading zeros
                              if required;

               ZZ = 00        and

               (SS)           is optional

          In the example given above, the host table address 10.2.0.124
          corresponds to the X.25 physical address 000001240200.

    Reynolds & Postel                                              [Page 51]

    RFC 1340                    Assigned Numbers                   July 1992

       2.  If h > 64 or h = 64, the host table address corresponds to the
       X.25 logical address

                                ZZZZ F RRRRRZZ (SS)

       where:

            ZZZZ = 0000    as required

            F = 1          because the address is a logical address;

            RRRRR          is a five decimal digit representation of
                           the result "r" of the calculation

                                    r = h * 256 + i

                           (Note that the decimal representation of
                           "r" will always require five digits);

            ZZ = 00        and

            (SS)           is optional

          Thus, the host table address 10.83.0.207 corresponds to the X.25
          logical address 000012145500.

       In both cases, the "n" and "l" fields of the host table address are
       not used.

                           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 MILNET uses the "link" field.  Further, there is an
       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.

                        ETHERNET VENDOR ADDRESS COMPONENTS

       Ethernet hardware addresses are 48 bits, expressed as 12 hexadecimal
       digits (0-9, plus A-F, capitalized).  These 12 hex digits consist of
       the first/left 6 digits (which should match the vendor of the
       Ethernet interface within the station) and the last/right 6 digits
       which specify the interface serial number for that interface vendor.

       Ethernet addresses might be written unhyphenated (e.g.,
       123456789ABC), or with one hyphen (e.g., 123456-789ABC), but should
       be written hyphenated by octets (e.g., 12-34-56-78-9A-BC).

       These addresses are physical station addresses, not multicast nor
       broadcast, so the second hex digit (reading from the left) will be
       even, not odd.

       At present, it is not clear how the IEEE assigns Ethernet block
       addresses.  Whether in blocks of 2**24 or 2**25, and whether
       multicasts are assigned with that block or separately.  A portion of
       the vendor block address is reportedly assigned serially, with the
       other portion intentionally assigned randomly.  If there is a global
       algorithm for which addresses are designated to be physical (in a
       chipset) versus logical (assigned in software), or globally-assigned
       versus locally-assigned addresses, some of the known addresses do not
       follow the scheme (e.g., AA0003; 02xxxx).

       Below are two tables describing the arrangement of protocol fields or
       type field assignments so that one could send NS Datagrams on the
       MILNET or Internet Datagrams on 10Mb Ethernet, and also protocol and
       type fields so one could encapsulate each kind of Datagram in the
       other.

                                 PRONET 80 TYPE NUMBERS

       Below is the current list of PRONET 80 Type Numbers.  Note: a
       protocol that is on this list does not necessarily mean that there is
       any implementation of it on ProNET.

       Of these, protocols 1, 14, and 20 are the only ones that have ever
       been seen in ARP packets.

       For reference, the header is (one byte/line):

               destination hardware address
               source hardware address
               data link header version (2)
               data link header protocol number
               data link header reserved (0)
               data link header reserved (0)

       Some protocols have been known to tuck stuff in the reserved fields.

       Those who need a protocol number on ProNET-10/80 should contact John
       Shriver (jas@proteon.com).

    PPP DLL PROTOCOL NUMBERS

       The Point-to-Point Protocol (PPP) Data Link Layer [146,147,175]
       contains a 16 bit Protocol field to identify the the encapsulated
       protocol.  The Protocol field is consistent with the ISO 3309 (HDLC)
       extension mechanism for Address fields.  All Protocols MUST be
       assigned such that the least significant bit of the most significant
       octet equals "0", and the least significant bit of the least
       significant octet equals "1".

       Protocol field values in the "0---" to "3---" range identify the
       network-layer protocol of specific datagrams, and values in the "8--
       -" to "b---" range identify datagrams belonging to the associated
       Network Control Protocol (NCP), if any.

       It is recommended that values in the "02--" to "1e--" and "--01" to
       "--1f" ranges not be assigned, as they are compression inefficient.

       Protocol field values in the "4---" to "7---" range are used for
       protocols with low volume traffic which have no associated NCP.

       Protocol field values in the "c---" to "e---" range identify
       datagrams as Control Protocols (such as LCP).
