Status of this Memo
This memo is an official status report on the numbers used in
protocols in the Internet community. Distribution of this memo is
unlimited.
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 Joyce Reynolds. If you are developing a protocol or application
that will require the use of a link, socket, port, protocol, etc.,
please contact Joyce 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" [91]. The more prominent and more generally used are
documented in the "DDN Protocol Handbook, Volume Two, DARPA Internet
Protocols" [36] prepared by the NIC. Other collections of older or
obsolete protocols are contained in the "Internet Protocol Transition
Workbook" [57], or in the "ARPANET Protocol Transition Handbook"
[38]. 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, Meno Park,
CA., 94025; or call: 1-800-235-3155.
In the entries below, the name and mailbox of the responsible
individual is indicated. The bracketed entry, e.g., [nn,iii], at the
Reynolds & Postel [Page 1]
RFC 1010 - Assigned Numbers May 1987
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.
The convention in the documentation of Internet Protocols is to
express numbers in decimal and to picture data in "big-endian" order
[14]. 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

| 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.

Port Numbers
PORT NUMBERS
Ports are used in the TCP [36,81] 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 [37,79].
To the extent possible, these same port assignments are used with the
ISO-TP4 [52].
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.
