 ASSIGNED NUMBERS


Status 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.

 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
 ARPA-Internet Protocols" [114]. The more prominent and more
 generally used are documented in the "DDN Protocol Handbook" [46]
 prepared by the NIC. Other collections of older or obsolete
 protocols are contained in the "Internet Protocol Transition Workbook
 [47], or in the "ARPANET Protocol Handbook" [48]. For further
 information on ordering the complete 1985 DDN Protocol Handbook,

RFC 990 November 1986
Assigned Numbers


 In the entries below the name and mailbox of the responsible
 individual is indicated. The 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, 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
 [131]. 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
 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
 | 5 | 6 | 7 | 8 |
 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
 | 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


Reynolds & Postel [Page 2]

RFC 990 November 1986
Assigned Numbers


 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.

RFC 990 November 1986
Network Numbers


 ASSIGNED NETWORK NUMBERS

 The network numbers listed here are used as internet addresses by the
 Internet Protocol (IP) [46,101]. 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.

 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 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.

 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 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.

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

 Class C Address







Reynolds & Postel [Page 4]

RFC 990 November 1986
Network Numbers


 The fourth type of address, class D, is used as a multicast
 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 Address

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

 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 B.ISI.EDU in dotted decimal is 010.003.000.052, or
 10.3.0.52.

 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 should not
 be listed in the working tables of either the ARPA-Internet or
 DDN-Internet hosts or gateways.



Reynolds & Postel [Page 5]

RFC 990 November 1986
Network Numbers


 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.

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

 For example, the address 0.0.0.37 could be interpreted as
 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 interpreted
 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 protocol
 to a network 127 address should loop back inside the host. No
 datagram "sent" to a network 127 address should ever appear on
 any network anywhere.

Port Numbers


 ASSIGNED PORT NUMBERS

 Ports are used in the TCP [46,102] 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 [46,100].

 To the extent possible, these same port assignments are used with the
 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 cleared
 to zero. The low order eight bits are specified here.

ARPANET Link Numbers


 ASSIGNED 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 [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. 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 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 a
 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.

 These numbers (and others) are assigned by the IEEE Standards Office.
 The address is: IEEE Standards Office, 345 East 47th Street, New
 York, N.Y. 10017, Attn: Vince Condello. Phone: (212) 705-7092.

 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 sent DOD-IP datagrams and other IP related
 protocols on 802 networks was developed.

 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 Address Resolution Protocol (ARP)) on IEEE 802 networks, the
 following new policy is established, which will replace the old
 policy (see RFC-960 and RFC-948 [138]).

 The new policy is for DDN and ARPA-Internet community to use 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 values of K1 and K2 must be assigned by the IEEE. There is
 already assigned a value of K1 that indicates that the 5-octet SNAP
 header follows. There may be a value of K2 that is already assigned
 that indicates that the last two octets of the SNAP header holds the
 EtherType.

 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 octet boundary.

 K1 is 170. The IEEE like to talk about things in 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.

 We believe that K2 is 0 (zero). This must be further investigated.
 As an interim measure use K2 = 0.

 The use of the IP LSAP (K1 = 6) is to be phased out as quickly as
 possible.

RFC 990 November 1986
Appendix A


 APPENDIX A

 Network 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 1-1-1-0)

 All addresses in this class are used for multicast addresses.

 Class E (highest-order bits 1-1-1-1)

 All addresses in this class are reserved for future use.

RFC 990 November 1986
Appendix A


 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
 4.3 UNIX software might be considered evidence of the latter.

 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.
