ASSIGNED NUMBERSStatus of this Memo
This memo is an official status report on the numbers used in protocols in the ARPA-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. The assignment of numbers is also handled by Joyce. If you are developing a protocol or application that will require the use of a link, socket, port, protocol, network number, etc., please contact Joyce to receive a number assignment.

ARPA mail: JKREYNOLDS@USC-ISIF.ARPAMost of the protocols mentioned here are documented in the RFC series of notes. The more prominent and more generally used are documented in the "Internet Protocol Transition Workbook" [[35](#ref-35 ""Internet Protocol Transition Workbook"")] or in the old "ARPANET Protocol Handbook" [[36](#ref-36 ""ARPANET Protocol Handbook"")] prepared by the NIC. Some of the items listed are undocumented. Further information on protocols can be found in the memo "Official ARPA-Internet Protocols" [[92](#ref-92 ""Official ARPA-Internet Protocols"")].
In all cases the name and mailbox of the responsible individual is indicated. In the lists that follow, a bracketed entry, e.g., [nn,iii], at the 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, letters are a NIC Ident as used in the WHOIS service.

Assigned Numbers RFC 943 Network Numbers
ASSIGNED NETWORK NUMBERSThe network numbers listed here are used as internet addresses by the Internet Protocol (IP) [[35](#ref-35 ""Internet Protocol Transition Workbook""),[80](#ref-80 ""Internet Protocol - DARPA Internet Program Protocol Specification"")]. The IP uses a 32-bit address field and divides that address into a network part and a "rest" or local address part. The division takes 3 forms or classes.
The first type of address, or class A, has a 7-bit network number
and a 24-bit local address. The highest-order bit is set to 0.
This allows 128 class A networks.

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

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

Class C Address
Note: No addresses are allowed with the three highest-order bits
set to 1-1-1. These addresses (sometimes called "class D") are
reserved.Reynolds & Postel [Page 2]
Assigned Numbers RFC 943 Network Numbers
One commonly used notation for internet host addresses divides the 32-bit address into four 8-bit fields and specifies the value of each field as a decimal number with the fields separated by periods. This is called the "dotted decimal" notation. For example, the internet address of USC-ISIF.ARPA in dotted decimal is 010.002.000.052, or 10.2.0.52.
The dotted decimal notation will be used in the listing of assigned network numbers. The class A networks will have nnn.rrr.rrr.rrr, the class B networks will have nnn.nnn.rrr.rrr, and the class C networks will have nnn.nnn.nnn.rrr, where nnn represents part or all of a 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 the allocation of network identifiers among the categories, a one-character code is placed to the left of the network number: R for Research, D for Defense, G for Government, and C for Commercial (see Appendix A for further details on this division of the network identification).
Network numbers are assigned for networks that are connected to the ARPA-Internet and DDN-Internet, and for independent networks that use the IP family protocols (these are usually commercial). These independent networks are marked with an asterisk preceding the number.
The administrators of independent networks must apply separately for permission to interconnect their network with either the ARPA-Internet of the DDN-Internet. Independent networks need not be listed in the working tables of either the ARPA-Internet or DDN-Internet hosts or gateways.
For various reasons, the assigned numbers of networks are sometimes changed. To ease the transition the old number will be listed for a transition period as well. These "old number" entries will be marked with a "T" following the number and preceding the name, and the network name will be suffixed "-TEMP".
Special Addresses:
In certain contexts, it is useful to have fixed addresses with
functional significance rather than as identifiers of specific
hosts. When such usage is called for, the address zero is to be
interpreted as meaning "this", as in "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 beReynolds & Postel [Page 3]
Assigned Numbers RFC 943 Network Numbers
interpreted as meaning all hosts on the network 128.9. Or, the
address 0.0.0.37 could be interpreted as meaning host 37 on this
network.Assigned Network Numbers

Assigned Numbers RFC 943 Port Numbers
ASSIGNED PORT NUMBERSPorts are used in the TCP [[35](#ref-35 ""Internet Protocol Transition Workbook""),[81](#ref-81 ""Transmission Control Protocol - DARPA Internet Program Protocol Specification"")] 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 [[35](#ref-35 ""Internet Protocol Transition Workbook""),[79](#ref-79 ""User Datagram Protocol"")].
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.

Assigned Numbers RFC 943 ARPANET Logical Addresses
ASSIGNED ARPANET LOGICAL ADDRESSESThe ARPANET facility for "logical addressing" is described in RFC 878 [[58](#ref-58 ""The ARPANET 1822L Host Access Protocol"")]. 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.

Assigned Numbers RFC 943 ARPANET Link Numbers
ASSIGNED ARPANET LINK NUMBERSThe 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 [[8](#ref-8 ""Specifications for the Interconnection of a Host and an IMP"")].
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.

96 01100000 DOD IP [[35](#ref-35 ""Internet Protocol Transition Workbook""),[79](#ref-79 ""User Datagram Protocol""),JBP]The IEEE 802.3 header does not have a type field to indicate what protocol is used at the next level. As a work around for this problem, one can put the Ethernet type field value in the IEEE 802.3 header's length field and use the following test to determine the appropriate processing on receipt.
If the value in the length field of the IEEE 802.3 header is greater than the Ethernet maximum packet length, then interpret the value as an Ethernet type field. Otherwise, interpret the packet as an IEEE 802.3 packet.

Assigned Numbers RFC 943 Appendix A
APPENDIX ANetwork Numbers
The network numbers in class A, B, and C network addresses are
allocated among Research, Defense, Government (Non-Defense) and
Commercial uses.
Class A (highest-order bit 0)
Research allocation: 8
Defense allocation: 24
Government allocation: 24
Commercial allocation: 94
Reserved Addresses: (0, 127)
Total 128
Class B (highest-order bits 1-0)
Research allocation: 1024
Defense allocation: 3072
Government allocation: 3072
Commercial allocation: 12286
Reserved Addresses: (0, 16383)
Total 16384
Class C (highest-order bits 1-1-0)
Research allocation: 65536
Defense allocation: 458725
Government allocation: 458725
Commercial allocation: 1572862
Reserved Addresses: (0, 2097151)
Total 2097152
Class D (highest-order bits 1-1-1)
All addresses in this class are reserved for future use.
Within the Research community, network identifiers will only be
granted to applicants who show evidence that they are acquiring
standard Bolt Beranek and Newman gateway software or have
implemented or are acquiring a gateway meeting the Exterior
Gateway Protocol requirements. Acquisition of the Berkeley BSD
4.2 UNIX software might be considered evidence of the latter.Reynolds & Postel [Page 49]
Assigned Numbers RFC 943 Appendix A
Experimental networks which later become operational need not be
renumbered. Rather, the identifiers could be moved from Research
to Defense, Government or Commercial status. Thus, network
identifiers may change state among Research, Defense, Government
and Commercial, but the number of identifiers allocated to each
use must remain within the limits indicated above. To make
possible this fluid assignment, the network identifier spaces are
not allocated by simple partition, but rather by specific
assignment.Protocol Identifiers
These assignments are shared by the four communities.Port Numbers
These assignments are shared by the four communities.ARPANET Link Numbers
These assignments are shared by the four communities.IP Version Numbers
These assignments are shared by the four communities.TCP, IP and Telnet Option Identifiers
These assignments are shared by the four communities.Implementation:
Joyce Reynolds is the coordinator for all number assignments.Reynolds & Postel [Page 50]
