   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.

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.

Top       Page 5 
         (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.

                           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.

                          REGISTERED PORT NUMBERS

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.

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 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)

Top       Page 31 
        Errors           0000
        Requests         0000 (4)
        Responses        <same as request> (4)

      Any IGP            0010                 (maximize reliability)

      EGP                0000

      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.
