Status of this
This memo is an official status report on the numbers used
protocols in the ARPA-Internet community
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. The more prominent and more generally used are
in the "Internet Protocol Transition Workbook" [31] or in the
"ARPANET Protocol Handbook" [32] prepared by the NIC. Some of
items listed are undocumented. Further information on protocols
be found in the memo "Official Protocols" [83].
In all cases the name and mailbox of the responsible individual
indicated. In the lists that follow, a bracketed entry, e.g.,
[31,iii], at the right hand margin of the page indicates a

"iii" cites the person. Whenever possible, this "iii" is a

ASSIGNED NETWORK
The network numbers listed here are used as internet addresses by
Internet Protocol (IP) [31,71]. 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

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

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

Assigned Numbers RFC 900
Network
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 USC-ISIF.ARPA in dotted decimal is 010.002.000.052,
10.2.0.52.
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 preceeding
number
The administrators of independent networks must apply separately
permission to interconnect their network with either
ARPA-Internet of the DDN-Internet. Independent networks need not
listed in the working tables of either the ARPA-Internet
DDN-Internet hosts or gateways
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 preceeding the name, and
network name will be suffixed "-TEMP".

Port
ASSIGNED PORT
Ports are used in the TCP [31,72] 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 [31,70].
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

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 [7].
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
