Status of this

This memo is an official status report on the numbers used
protocols in the ARPA-Internet community. Distribution of this
is unlimited

This Network Working Group Request for Comments documents
currently assigned values from several series of numbers used
network protocol implementations. This RFC will be
periodically, and in any case current information can be
from Joyce Reynolds. The assignment of numbers is also handled
Joyce. If you are developing a protocol or application that
require the use of a link, socket, port, protocol, network number
etc., please contact Joyce to receive a number assignment

Most of the protocols mentioned here are documented in the RFC
of notes. Some of the items listed are undocumented.
information on protocols can be found in the memo "
ARPA-Internet Protocols" [114]. The more prominent and
generally used are documented in the "DDN Protocol Handbook" [46]
prepared by the NIC. Other collections of older or
protocols are contained in the "Internet Protocol Transition
[47], or in the "ARPANET Protocol Handbook" [48]. For

RFC 990 November 1986
Assigned

In the entries below the name and mailbox of the
individual is indicated. The bracketed entry, e.g., [nn,iii], at
right hand margin of the page indicates a reference for the
protocol, where the number ("nn") cites the document and the
("iii") cites the person. Whenever possible, the letters are a
Ident as used in the WhoIs (NICNAME) service

The convention in the documentation of Internet Protocols is
express numbers in decimal and to picture data in "big-endian"
[131]. That is, fields are described left to right, with the
significant octet on the left and the least significant octet on
right

The order of transmission of the header and data described in
document is resolved to the octet level. Whenever a diagram shows
group of octets, the order of transmission of those octets is
normal order in which they are read in English. For example, in
following diagram the octets are transmitted in the order they
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

Transmission Order of

Whenever an octet represents a numeric quantity the left most bit
the diagram is the high order or most significant bit. That is,
bit labeled 0 is the most significant bit. For example,
following diagram represents the value 170 (decimal).

0 1 2 3 4 5 6 7

Similarly, whenever a multi-octet field represents a numeric

the left most bit of the whole field is the most significant bit
When a multi-octet quantity is transmitted the most significant
is transmitted first

RFC 990 November 1986
Network

ASSIGNED NETWORK

The network numbers listed here are used as internet addresses by
Internet Protocol (IP) [46,101]. The IP uses a 32-bit address
and divides that address into a network part and a "rest" or
address part. The division takes 3 forms or classes

The first type of address, or class A, has a 7-bit network
and a 24-bit local address. The highest-order bit is set to 0.
This allows 128 class A networks

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
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|0| NETWORK | Local Address |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

Class A

The second type of address, class B, has a 14-bit network
and a 16-bit local address. The two highest-order bits are set
1-0. This allows 16,384 class B networks

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 0| NETWORK | Local Address |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

Class B

The third type of address, class C, has a 21-bit network
and a 8-bit local address. The three highest-order bits are
to 1-1-0. This allows 2,097,152 class C networks

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

+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

Class C

Reynolds & Postel [Page 4]

RFC 990 November 1986
Network

The fourth type of address, class D, is used as a
address [44]. The four highest-order bits are set to 1-1-1-0.

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 1 1 0| multicast address |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

Class D

Note: No addresses are allowed with the four highest-order
set to 1-1-1-1. These addresses, called "class E", are reserved

One commonly used notation for internet host addresses divides
32-bit address into four 8-bit fields and specifies the value of
field as a decimal number with the fields separated by periods.
is called the "dotted decimal" notation. For example, the
address of B.ISI.EDU in dotted decimal is 010.003.000.052,
10.3.0.52.

The dotted decimal notation will be used in the listing of
network numbers. The class A networks will have nnn.rrr.rrr.rrr,
class B networks will have nnn.nnn.rrr.rrr, and the class C
will have nnn.nnn.nnn.rrr, where nnn represents part or all of
network number and rrr represents part or all of a local address

There are four catagories of users of Internet Addresses: Research
Defense, Government (Non-Defense), and Commercial. To reflect
allocation of network identifiers among the categories,
one-character code is placed to the left of the network number: R
Research, D for Defense, G for Government, and C for Commercial (
Appendix A for further details on this division of the
identification).

Network numbers are assigned for networks that are connected to
ARPA-Internet and DDN-Internet, and for independent networks that
the IP family protocols (these are usually commercial).
independent networks are marked with an asterisk preceding
number

The administrators of independent networks must apply separately
permission to interconnect their network with either
ARPA-Internet of the DDN-Internet. Independent networks should
be listed in the working tables of either the ARPA-Internet
DDN-Internet hosts or gateways

Reynolds & Postel [Page 5]

RFC 990 November 1986
Network

For various reasons, the assigned numbers of networks are
changed. To ease the transition the old number will be listed for
transition period as well. These "old number" entries will be
with a "T" following the number and preceding the name, and
network name will be suffixed "-TEMP".

Special Addresses

In certain contexts, it is useful to have fixed addresses
functional significance rather than as identifiers of
hosts

The address zero is to be interpreted as meaning "this", as
"this network".

For example, the address 0.0.0.37 could be interpreted
meaning host 37 on this network

The address of all ones are to be interpreted as meaning "all",
as in "all hosts".

For example, the address 128.9.255.255 could be
as meaning all hosts on the network 128.9.

The class A network number 127 is assigned the "loopback
function, that is, a datagram sent by a higher level
to a network 127 address should loop back inside the host.
datagram "sent" to a network 127 address should ever appear
any network anywhere

Port

ASSIGNED PORT

Ports are used in the TCP [46,102] to name the ends of
connections which carry long term conversations. For the purpose
providing services to unknown callers, a service contact port
defined. This list specifies the port used by the server process
its contact port. The contact port is sometimes called
"well-known port".

To the extent possible, these same port assignments are used with
UDP [46,100].

To the extent possible, these same port assignments are used with
ISO-TP4 [64].

The assigned ports use a small portion of the possible port numbers
The assigned ports have all except the low order eight bits
to zero. The low order eight bits are specified here

ARPANET Link

ASSIGNED ARPANET LINK

The word "link" here refers to a field in the original
Host/IMP interface leader. The link was originally defined as
8-bit field. Later specifications defined this field as
"message-id" with a length of 12 bits. The name link now refers
the high order 8 bits of this 12-bit message-id field. The Host/
interface is defined in BBN Report 1822 [10].

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.
sender may use the sub-link in any way he chooses (it is returned
the RFNM by the destination IMP), the receiver should ignore
sub-link
