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.

  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):

           |                     |
           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
  Protocol     Delay    Throughput  Reliability
  TELNET (1)    1           0           0

                           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).

                         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 ([email protected]).
