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.

ARPANET Logical Addresses
ARPANET 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 Joyce Reynolds. Assignments for
other logical host addresses are made by the NIC.

ARPANET Link Numbers
ARPANET 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.

IEEE 802 SAP Numbers
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 on 802 networks was developed.
Reynolds & Postel [Page 12]
RFC 1010 - Assigned Numbers May 1987
IEEE 802 SAP Numbers
Due to some evolution of the IEEE 802.2 standards and the need to
provide for a standard way to do additional DoD-IP related protocols
(such as the Address Resolution Protocol (ARP) on IEEE 802 network,
the following new policy is established, which will replace the old
policy (see RFC 960 and RFC 948 [108]).
The new policy is for the Internet community to use the IEEE 802.2
encapsulation on 802.3, 802.4, and 802.5 networks by using the SNAP
with an organization code indicating that the following 16 bits
specify the EtherType code (where IP = 2048 (0800 hex), see Ethernet
Numbers of Interest).
Header
...--------+--------+--------+
MAC Header| Length | 802.{3/4/5} MAC
...--------+--------+--------+
+--------+--------+--------+
| Dsap=K1| Ssap=K1| control| 802.2 SAP
+--------+--------+--------+
+--------+--------+---------+--------+--------+
|protocol id or org code =K2| Ether Type | 802.2 SNAP
+--------+--------+---------+--------+--------+
The total length of the SAP Header and the SNAP header is 8-octets,
making the 802.2 protocol overhead come out on a nice boundary.
K1 is 170. The IEEE likes to talk about things in little-endian bit
transmission order and specifies this value as 01010101. In
big-endian order, as used in Internet specifications, this becomes
10101010 binary, or AA hex, or 170 decimal.
K2 is 0 (zero).
The use of the IP LSAP (K1 = 6) is to be phased out as quickly as
possible.

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.
