   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

   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

   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.

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> }


         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

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.

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

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

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

The Registered Ports are in the range 1024-65535.

                             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

   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)

        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)

      Any IGP            0010                 (maximize reliability)

      SNMP               0010                 (maximize reliability)

      BOOTP              0000


      (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

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

                               BOOTP PARAMETERS

   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:

   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, 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

                         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: "", n=10, h=2,
   l=0, and i=124.  To convert a host table address to a MILNET X.25

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

                             ZZZZ F IIIHHZZ (SS)


           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
      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)


        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 corresponds to the X.25
      logical address 000012145500.

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

   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

   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.

RFC 1340                    Assigned Numbers                   July 1992


   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 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.

   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".

   It is recommended that values in the "02--" to "1e--" and "--01" to

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