   This etwork  orking  roup 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 ny case current information can be obtained from
   the Internet ssigned Numbers Authority (IANA).  If you are developing
   a protocol or application that will require the use of a link, socket,
   port, protocol, etc., please ontact  he IANA to receive a number

   Most f the protocols mentioned here  re documented in the RFC series
   of notes.  Some of the items isted are undocumented.  Further
   information on protocols can e found in the  emo "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 he page indicates a reference for the listed
   protocol, where the number ("nn") cites the document nd the  etters
   ("iii") cites the person.  Whenever possible, the letters are a NIC
   Ident as used in the hoIs (NICNAME)  ervice.

Data Notations

   The convention in the documentation of Internet Protocols is o
   express numbers in decimal and to picture data in "big-endian" order
   [21].  That is, fields are described eft to  ight, with the  ost
   significant octet on he left and the least significant octet on the
   The order of ransmission of  he header and data described in this
   document is resolved o the octet level.  Whenever a  iagram  hows a
   group of octets, the rder of transmission of those octets is the
   normal order n which they are read in English.  For  xample, in the
   following diagram the octets re transmitted  n 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  numeric quantity the left most bit in
   the diagram is the high order or most significant bit.  That s, the
   bit labeled 0 is the ost significant bit.  For example, the
   following diagram represents he value 170 (decimal).
                     0 1 2 3 4 5 6 7
                    |1 0 1 0 1 0 1 0|
                   Significance f Bits
   Similarly, whenever a multi-octet field represents a umeric  uantity
   the left most bit of he whole field  s the most significant  it.
   When  multi-octet quantity is transmitted the most significant octet
   is transmitted first.

Special ddresses:

   There are five classes of IP ddresses: Class A through Class E
   [119].  Of these, Class E addresses are reserved for xperimental
   use. A gateway which is not  articipating in these experiments must
   ignore all datagrams ith a Class E destination IP address.   CMP
   Destination Unreachable or ICMP Redirect messages must not result
   from eceiving such datagrams.
   There are certain special cases for IP addresses [11].  These special
   cases can be oncisely summarized using the earlier notation  or 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 ield contains all 1 bits. Some common special cases are s follows:

        (a)   {0, 0}
           This host on this network.   an 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. an 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  ddress.
        (g)   {127, <any>}

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

                      VERSION NUMBERS

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

The Well Known Ports are controlled and ssigned by the  ANA and on most
systems an 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 ong 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 ort.  The contact port  s sometimes called the  well-known

To the extent possible, hese same port ssignments are sed 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 he IANA has been expanded to the range 0-1023.

The Registered Ports are not controlled y the IANA and  n most  ystems
can be used by ordinary ser processes or programs executed by ordinary

Ports are used in the TCP [45,106] to name the ends of logical connections which carry ong 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 ort. 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, hese same port ssignments are sed with the

UDP [46,104].

The Registered Ports are in the ange 1024-65535.

These addresses are listed in the omain Name Service under MCAST.NET nd 224.IN-ADDR.ARPA.

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


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

   The address block in EEE binary is (which is in bit  ransmission
  1. 0000 0000 0000 0111 010
   In the normal Internet dotted decimal notation this is 0.0.94 since
   the bytes are transmitted higher order first nd bits within  ytes
   are transmitted lower order first (see "Data otation" in the
   IEEE SMA/CD  nd Token Bus bit transmission order: 00 00 5E

                     IP OS PARAMETERS

This ocuments 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, nd low  ost; in each case, the  OS value is used to
   indicate "better".  Only one OS value or property can be requested
   in any one IP datagram.
   Generally, protocols hich are involved in direct interaction with a
   human should elect low delay, while  ata transfers which may involve
   large blocks f data  re need high throughput.  Finally, high
   reliability is most important for datagram-based Internet management
   Application protocols not included in these tables should be ble to
   make ppropriate choice of low delay  8 decimal, 1000 binary) or high
   throughput (4 decimail, 0100 inary).

The following are recommended values or TOS:

          ----- ype-of-Service  alue -----
      Protocol   TOS Value
      TELNET (1)        1000          (minimize elay)


        ontrol   1000         (minimize elay)
        ata (2) 0100          (maximize hroughput)
      TFTP       1000         (minimize elay)

SMTP (3)

        ommand  hase    1000          (minimize elay)
        ATA phase       0100          (maximize hroughput)

        CP Query        0000
        one Transfer    0100          (maximize hroughput)

      Any IGP    0010         (maximize eliability)
      EGP        0000
      SNMP       0010         (maximize eliability)
      BOOTP      0000


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

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

      (3) If the implementation oes not support changing the TOS during
      the lifetime of the connection, then the recommended TOS on
      opening the connection is he default TOS  0000).
      (4) Although ICMP equest  essages are normally sent with  he
      default TOS, there are sometimes good reasons why hey would be
      sent with ome other TOS value.  An ICMP response  lways uses the
      same TOS value as as used in the  orresponding ICMP request

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

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 nd Indentification of Management
   Information for TCP/IP-based nternets" (SMI) RFC-1155 [120], and the
   "Management Information Base or Network Management of TCP/IP-based
   Internets" (MIB-II) [121].
   The SMI includes the rovision for panrameters or codes to indicate
   experimental r private data  tructures.  These parameter assignments
   are listed here.
   The older "Simple Gateway Monitoring rotocol" (SGMP) RFC-1028 [37]
   also efined   data structure.  The parameter assignments used with
   SGMP re included here for hist orical completeness.

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

   The MILNET facility for "logical addressing" s described in  FC-878
   [57] nd RFC-1005 [109].  A portion of the possible logical addresses
   are reserved or standard uses.
   There are 49,152 possible logical host addresses.  Of these, 56 are
   reserved for ssignment to well-known functions.  Assignments for
   well-known functions re made by the  ANA.  Assignments for other
   logical host ddresses are made by the NIC.

   The word "link" here efers to a field in the original MILNET
   Host/IMP interface leader.  The link as originally defined as an 8-
   bit field.  Later specifications defined this field as the "message-
   id" with a length of 2 bits.  The name link  ow refers to the high
   order 8 bits f this  2-bit message-id field.  The Host/IMP interface
   is defined in BBN Report 1822 [2].
   The low-order 4 bits f the message-id field  re 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 he

   All MILNET hosts are ssigned addresses by the Defense Data Network
   (DDN).  The address of a MILNET host ay be obtained  rom the Network
   Information Center (NIC), represented as an ASCII text string in what
   is called "host table format".  This ection  escribes the process by
   which MILNET .25 addresses may be derived from addresses in  he NIC
   host able format.
   A NIC host table address consists of he ASCII text string
   representations of four decimal numbers separated by eriods,
   corresponding to the our octeted of   thirty-two bit Internet
   address.  The four decimal numbers are referred to in this section as
   "n", h' "l", and "i".  Thus, a host  able address may be represented
   as: "n.h.l.i".  Each f these four numbers will have  ither one, two,
   or three decimal digits and will never have a value greater than 255.
   For example, n the host table, address: "", n=10,  =2,
   l=0, nd i=124.  To convert a host table address to a MILNET  .25

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



          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 f required;
          HH      is a two decimal digit representation f "h",
                  right-adjusted and padded with leading zeros
                  if required;
          ZZ =  0        and
          (SS)    is optional

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

   2.  If h > 64 or h = 4, the  ost table address corresponds to the
   X.25 ogical  ddress



        ZZZ = 0000    as required

= 1 because the address is a ogical ddress;

        RRRR          is a five decimal digit representation of
               the result "r" of the calculation
                        r = h * 56 + i

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

        Z = 00        and
        SS)           is optional

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

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

   Some f the networks  f all classes are IEEE  02 Networks.  These
   systems may use a Link Service Access Point (LSAP) field in much the
   same ay the  ILNET uses the  link" field.  Further,  here is an
   extension of he LSAP header  alled the Sub-Network Access Protocol
   The IEEE likes to describe numbers in binary n bit transmission
   order, which s the opposite  f the big-endian order  sed throughout

   At an ad hoc pecial  ession  n "IEEE 802 Networks and ARP",  eld
   during the TCP Vendors Workshop (August 1986), an approach to a
   consistent way to send DoD-IP datagrams and other IP elated
   protocols (such as the Address Resolution Protocol (ARP)) on 02
   networks was eveloped, using the SNAP extension (see RFC-1042 [90]).
   Many f the networks  f all classes are Ethernets (10Mb) or
   Experimental thernets (3Mb).  These  ystems  se a message "type"
   field in much the same way the ARPANET uses the "link" field.

   The standard or transmission of IP datagrams over Ethernets  nd
   Experimental thernets is specified in RFC-894 [61] and RFC-895 [91]
   NOTE:  Ethernet 48-bit address blocks are assigned by the IEEE.
   IEEE tandards Office, 345 East 47th  treet,  ew York, N.Y. 10017,
   Attn: Vince Condello.  Phone: (212) 705-7092.


Ethernet hardware addresses are 48 bits, expressed as 12 hexadecimal digits (0-9, lus 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 endor.

   Ethernet addresses might be written unhyphenated (e.g.,
   123456789ABC), or with one hyphen (e.g., 123456-789ABC), but hould
   be written hyphenated by octets (e.g., 12-34-56-78-9A-BC).
   These addresses are physical tation  ddresses, not multicast nor
   broadcast, so the second hex igit (reading from the  eft) 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 hether multicasts are assigned with hat block or separately. A portion of the vendor block address is reportedly assigned serially, with the other portion intentionally assigned andomly. If there is a global algorithm for which addresses are designated o be physical (in a chipset) versus logical (assigned in oftware), or globally-assigned versus locally-assigned addresses, some of the known ddresses do not follow the scheme (e.g., AA0003; 02xxxx).

   Below is the urrent  ist of  RONET 80 Type Numbers.  Note: a
   protocol that is on this list does not necessarily mean that here is
   any implementation of it on ProNET.
   Of these, protocols 1, 14, and 20 are the only ones that have ever
   been een in  RP packets.

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

          destination hardware  ddress
          source hardware address
          data  ink header version (2)
          data  ink header protocol number
          data  ink header reserved (0)
          data  ink header reserved (0)
   Some rotocols have been known to tuck stuff  n the reserved  ields.

   The Point-to-Point Protocol (PPP) Data Link Layer [146,147,175]
   contains a 16 bit Protocol field to identify he the  ncapsulated
   protocol.  The Protocol field is consistent with the SO 3309 (HDLC)
   extension mechanism for Address fields.  All rotocols MUST be
   assigned such that the least ignificant bit  f 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  he
   network-layer protocol of specific datagrams, and values in the "8--
   -" to "b---" ange 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 ssigned, as they are compression inefficient.
   Protocol field values in the 4---" to "7---" range are used  or
   protocols with low volume traffic which have o associated NCP.
   Protocol field values in the c---" to "e---" range identify
   datagrams as ontrol  rotocols (such  s LCP).
