RFC 1700
Assigned Numbers
Network Working Group J. Reynolds Request for Comments: 1700 J. Postel STD: 2 ISI Obsoletes RFCs: 1340, 1060, 1010, 990, 960, October 1994 943, 923, 900, 870, 820, 790, 776, 770, 762, 758,755, 750, 739, 604, 503, 433, 349 Obsoletes IENs: 127, 117, 93 Category: Standards Track ASSIGNED NUMBERS 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. OVERVIEW This RFC is 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 RFC has 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 <iana@isi.edu>.
INTRODUCTION The files in this directory document the currently assigned values for several series of numbers used in network protocol implementations. ftp://ftp.isi.edu/in-notes/iana/assignments 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 parameters. 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 <iana@isi.edu>. Requests for SNMP network management private enterprise number assignments should be sent to <iana-mib@isi.edu>. 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. Joyce K. Reynolds Internet Assigned Numbers Authority USC - Information Sciences Institute 4676 Admiralty Way Marina del Rey, California 90292-6695 Electronic mail: IANA@ISI.EDU Phone: +1 310-822-1511
Most of the protocols 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, "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
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. 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
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.

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 [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.
