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 "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.

   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.

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> }

            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.

         (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.

                              VERSION NUMBERS

   In the Internet Protocol (IP) [45,105] there is a field to identify
   the version of the internetwork general protocol.  This field is 4
   bits in size.

                                 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
port".

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.

   Host Extensions for IP Multicasting (RFC-1112) [43] specifies the
   extensions required of a host implementation of the Internet Protocol
   (IP) to support multicasting.  Current addresses are listed below.

      Note that when used on an Ethernet or IEEE 802 network, the 23
      low-order bits of the IP Multicast address are placed in the low-
      order 23 bits of the Ethernet or IEEE 802 net multicast address
      1.0.94.0.0.0.  See the next section on "IANA ETHERNET ADDRESS
      BLOCK".

                         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

   IEEE Token Ring bit transmission order: 00 00 7A

   Appearance on the wire (bits transmitted from left to right):

       0                           23                            47
       |                           |                             |

       |                                     |
       Multicast Bit                         0 = Internet Multicast
                                             1 = Assigned by IANA for
                                                 other uses

   Appearance in memory (bits transmitted right-to-left within octets,
   octets transmitted left-to-right):

       0                           23                            47
       |                           |                             |
       0000 0001 0000 0000 0101 1110 0xxx xxxx xxxx xxxx xxxx xxxx
               |                     |
               Multicast Bit         0 = Internet Multicast
                                     1 = Assigned by IANA for other uses

   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 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
   on.

   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 (1 0 0) or high throughput (0 1
   0).

   The following are recommended values for TOS:

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

                    Low        High         High

      (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 (0,0,0).

                         IP TIME TO LIVE PARAMETER

   The current recommended default TTL for the Internet Protocol (IP)
   RFC-791 [45,105] is 32.

                         DOMAIN SYSTEM PARAMETERS

   The Internet Domain Naming System (DOMAIN) includes several
   parameters.  These are documented in RFC-1034, [81] and RFC-1035
   [82].  The CLASS parameter is listed here.  The per CLASS parameters
   are defined in separate RFCs as indicated.

                               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).

   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-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.

                     ARPANET AND MILNET LOGICAL ADDRESSES

   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
   sub-link.

                   ARPANET AND 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.

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 ARPANET 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.

   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:
   Ms. Fonda Pallone, (408) 737-4652.

   The standard for transmission of IP datagrams over Ethernets and
   Experimental Ethernets is specified in RFC-894 [61] and RFC-895 [91]
   respectively.

   NOTE:  Ethernet 48-bit address blocks are assigned by the IEEE.

   IEEE Standards Office, 345 East 47th Street, New York, N.Y. 10017,
   Attn: Vince Condello.  Phone: (212) 705-7092.

                    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).

                      PROTOCOL/TYPE FIELD ASSIGNMENTS

   Below are two tables describing the arrangement of protocol fields or
   type field assignments so that one could send NS Datagrams on the
   ARPANET 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).
