   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 "Official Internet
   Protocols" [118].  The more prominent and more generally used are
   documented in the "DDN Protocol Handbook, Volume Two, DARPA Internet
   Protocols" [45] prepared by the NIC.  Other collections of older or
   obsolete protocols are contained in the "Internet Protocol Transition
   Workbook" [76], or in the "ARPANET Protocol Transition Handbook"
   [47].  For further information on ordering the complete 1985 DDN
   Protocol Handbook, write: SRI International (SRI-NIC), DDN Network
   Information Center, Room EJ291, 333 Ravenswood Avenue, Menlo Park,
   CA., 94025; or call: 1-800-235-3155.  Also, the Internet Activities
   Board (IAB) publishes the "IAB Official Protocol Standards" [62],
   which describes the state of standardization of protocols used in the
   Internet.  This document is issued quarterly.  Current copies may be
   obtained from the DDN Network Information Center or from the IANA.

   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

Reynolds & Postel                                               [Page 3]

RFC 1060                    Assigned Numbers                  March 1990

   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.

Special Addresses:

   There are five classes of IP addresses:  Class A through Class E
   [119].  Of these, Class D and Class E addresses are reserved for
   experimental use.  A gateway which is not participating in these
   experiments must ignore all datagrams with a Class D or 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.

RFC 1060                    Assigned Numbers                  March 1990

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

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

         (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.

                                 PORT NUMBERS

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].

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.

   Port Assignments:

                             IP TOS PARAMETERS

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

   There are three binary TOS attributes: low delay, high throughput,
   and high reliability; in each case, an attribute bit is turned on to
   indicate "better".  The three attributes cannot all be optimized
   simultanously, and in fact the TOS algorithms that have been
   discussed tend to make "better" values of the attributes mutually
   exclusive.  Therefore, the recommended values have at most one bit

   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 (1 0 0) or high throughput (0 1

   The following are recommended values for TOS:

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

                               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] proposes an addition to
   the Bootstrap Protocol (BOOTP).

   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-1098 [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-1065 [120], and the
   "Management Information Base for Network Management of TCP/IP-based
   Internets" (MIB) [121].

   The SMI includes the provision for parameters 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 ARPANET 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.

                       ARPANET AND MILNET 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 [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

   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.

                            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.

                       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 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.

   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 send DoD-IP datagrams and other IP related
   protocols (such as the Address Resolution Protocol (ARP)) on 802
   networks was developed, using the SNAP extension (see RFC-1010 and
   RFC-1042 [90]).

                       ETHERNET NUMBERS OF INTEREST

   Many of the networks of all classes are Ethernets (10Mb) or
   Experimental Ethernets (3Mb).  These systems use a message "type"
   field in much the same way the ARPANET uses the "link" field.

   If you need an Ethernet type, contact the Xerox Corporation, Xerox
   Systems Institute, 475 Oakmead Parkway, Sunnyvale, CA 94086, Attn:

RFC 1060                    Assigned Numbers                  March 1990


   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).

                             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.
