Status of this Memo

This memo is a status report on the parameters (i.e., numbers and
keyWords) used in PRotocols in the Internet community. Distribution
of this memo is unlimited.


This RFCis a snapshot of the ongoing process of the assignment of
protocol parameters for the Internet protocol suite. To make the
current information readily available the assignments are kept up-to-
date in a set of online text files. This RFChas been assembled by
catinating these files together with a minimum of formatting "glue".
The authors appologize for the somewhat rougher formatting and style
than is typical of most RFCs.

We eXPect that various readers will notice specific items that should be
corrected. Please send any specific corrections via email to
<[email protected]>.


The files in this Directory document the currently assigned values for
several series of numbers used in network protocol implementations.


The Internet Assigned Numbers Authority (IANA) is the central
coordinator for the assignment of unique parameter values for Internet
protocols. The IANA is chartered by the Internet Society (ISOC) and
the Federal Network Council (FNC) to act as the clearinghouse to
assign and coordinate the use of numerous Internet protocol

The Internet protocol suite, as defined by the Internet Engineering
Task Force (IETF) and its steering group (the IESG), contains numerous
parameters, such as internet addresses, domain names, autonomous
system numbers (used in some routing protocols), protocol numbers,
port numbers, management information base object identifiers,
including private enterprise numbers, and many others.

The common use of the Internet protocols by the Internet community
requires that the particular values used in these parameter fields be
assigned uniquely. It is the task of the IANA to make those unique
assignments as requested and to maintain a registry of the currently
assigned values.

Requests for parameter assignments (protocols, ports, etc.) should be

sent to <[email protected]>.

Requests for SNMP network management private enterprise number
assignments should be sent to <[email protected]>.

The IANA is located at and Operated by the Information Sciences
Institute (ISI) of the University of Southern California (USC).

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 are documented in the RFCseries of notes. Some
of the items listed are undocumented. Further information on
protocols can be found in the memo, "Internet Official Protocol
Standards" (STD 1).

Data Notations

The convention in the documentation of Internet Protocols is to
express numbers in decimal and to picture data in "big-endian" order
[COHEN]. 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. Of
these, Classes A, B, and C are used for unicast addresses, Class D is
used for multicast addresses, and Class E addresses are reserved for
future use.

With the advent of classless addressing [CIDR1, CIDR2], the

network-number part of an address may be of any length, and the whole
notion of address classes becomes less important.

There are certain special cases for IP addresses. These special cases
can be concisely summarized using the earlier notation for an IP

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.

(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.

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 [RFC793] 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 [RFC768].

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.

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 users.

Ports are used in the TCP [RFC793] 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 [RFC768].

The Registered Ports are in the range 1024-65535.
