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 the Internet Assigned Numbers Authority (IANA). If you are developing a protocol or application that will require the use of a link, socket, port, protocol, etc., please contact the IANA 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 "IAB Official Protocol Standards" [[62](#ref-62 ""IAB Official Protocol Standards"")].
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.

Data Notations
The convention in the documentation of Internet Protocols is to express numbers in decimal and to picture data in "big-endian" order [[21](#ref-21 ""On Holy Wars and a Plea for Peace"")]. 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
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| 1 | 2 | 3 | 4 |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| 5 | 6 | 7 | 8 |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| 9 | 10 | 11 | 12 |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
Transmission Order of BytesWhenever 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 BitsSimilarly, 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.

Special Addresses:
There are five classes of IP addresses: Class A through Class E [[119](#ref-119 ""Internet Numbers"")]. Of these, Class E addresses are reserved for experimental use. A gateway which is not participating in these experiments must ignore all datagrams with a Class E destination IP address. ICMP Destination Unreachable or ICMP Redirect messages must not result from receiving such datagrams.
There are certain special cases for IP addresses [[11](#ref-11 ""Requirements for Internet Gateways"")]. These special cases can be concisely summarized using the earlier notation for an IP address:
IP-address ::= { <Network-number>, <Host-number> }
or
IP-address ::= { <Network-number>, <Subnet-number>,
<Host-number> }if we also use the notation "-1" to mean the field contains all 1 bits. Some common special cases are as follows:
(a) {0, 0}
This host on this network. Can only be used as a source
address (see note later).
(b) {0, <Host-number>}
Specified host on this network. Can only be used as a
source address.
(c) { -1, -1}
Limited broadcast. Can only be used as a destination
address, and a datagram with this address must never be
forwarded outside the (sub-)net of the source.
(d) {<Network-number>, -1}
Directed broadcast to specified network. Can only be used
as a destination address.
(e) {<Network-number>, <Subnet-number>, -1}
Directed broadcast to specified subnet. Can only be used as
a destination address.Reynolds & Postel [Page 4]
RFC 1340 Assigned Numbers July 1992
(f) {<Network-number>, -1, -1}
Directed broadcast to all subnets of specified subnetted
network. Can only be used as a destination address.
(g) {127, <any>}
Internal host loopback address. Should never appear outside
a host.Reynolds & Postel [Page 5]

RFC 1340 Assigned Numbers July 1992
WELL KNOWN PORT NUMBERSThe Well Known Ports are controlled and assigned by the IANA and on most systems can only be used by system (or root) processes or by programs executed by privileged users.
Ports are used in the TCP [[45](#ref-45 ""DDN Protocol Handbook""),[106](#ref-106 ""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 [[46](#ref-46 ""Internet Protocol Transition Workbook""),[104](#ref-104 ""User Datagram Protocol"")].
The assigned ports use a small portion of the possible port numbers. For many years the assigned ports were in the range 0-255. Recently, the range for assigned ports managed by the IANA has been expanded to the range 0-1023.

RFC 1340 Assigned Numbers July 1992
REGISTERED PORT NUMBERSThe Registered Ports are not controlled by the IANA and on most systems can be used by ordinary user processes or programs executed by ordinary users.
Ports are used in the TCP [[45](#ref-45 ""DDN Protocol Handbook""),[106](#ref-106 ""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. While the IANA can not control uses of these ports it does register or list uses of these ports as a convienence to the community.
To the extent possible, these same port assignments are used with the UDP [[46](#ref-46 ""Internet Protocol Transition Workbook""),[104](#ref-104 ""User Datagram Protocol"")].
The Registered Ports are in the range 1024-65535.

RFC 1340 Assigned Numbers July 1992
IANA ETHERNET ADDRESS BLOCKThe IANA owns an Ethernet address block which may be used for multicast address asignments or other special purposes.
The address block in IEEE binary is (which is in bit transmission order):
0000 0000 0000 0000 0111 1010In the normal Internet dotted decimal notation this is 0.0.94 since the bytes are transmitted higher order first and bits within bytes are transmitted lower order first (see "Data Notation" in the Introduction).
IEEE CSMA/CD and Token Bus bit transmission order: 00 00 5E
IEEE Token Ring bit transmission order: 00 00 7A
Appearance on the wire (bits transmitted from left to right):
0 23 47
| | |
1000 0000 0000 0000 0111 1010 xxxx xxx0 xxxx xxxx xxxx xxxx
| |
Multicast Bit 0 = Internet Multicast
1 = Assigned by IANA for
other usesAppearance in memory (bits transmitted right-to-left within octets, octets transmitted left-to-right):
0 23 47
| | |
0000 0001 0000 0000 0101 1110 0xxx xxxx xxxx xxxx xxxx xxxx
| |
Multicast Bit 0 = Internet Multicast
1 = Assigned by IANA for other usesThe latter representation corresponds to the Internet standard bit- order, and is the format that most programmers have to deal with. Using this representation, the range of Internet Multicast addresses is:
01-00-5E-00-00-00 to 01-00-5E-7F-FF-FF in hex, or
1.0.94.0.0.0 to 1.0.94.127.255.255 in dotted decimalReynolds & Postel [Page 29]
RFC 1340 Assigned Numbers July 1992
IP TOS PARAMETERSThis documents the default Type-of-Service values that are currently recommended for the most important Internet protocols.
There are four assigned TOS values: low delay, high throughput, high reliability, and low cost; in each case, the TOS value is used to indicate "better". Only one TOS value or property can be requested in any one IP datagram.
Generally, protocols which are involved in direct interaction with a human should select low delay, while data transfers which may involve large blocks of data are need high throughput. Finally, high reliability is most important for datagram-based Internet management functions.
Application protocols not included in these tables should be able to make appropriate choice of low delay (8 decimal, 1000 binary) or high throughput (4 decimail, 0100 binary).
The following are recommended values for TOS:
----- Type-of-Service Value -----
Protocol TOS Value
TELNET (1) 1000 (minimize delay)
FTP
Control 1000 (minimize delay)
Data (2) 0100 (maximize throughput)
TFTP 1000 (minimize delay)
SMTP (3)
Command phase 1000 (minimize delay)
DATA phase 0100 (maximize throughput)
Domain Name Service
UDP Query 1000 (minimize delay)
TCP Query 0000
Zone Transfer 0100 (maximize throughput)
NNTP 0001 (minimize monetary cost)Reynolds & Postel [Page 30]
RFC 1340 Assigned Numbers July 1992
ICMP
Errors 0000
Requests 0000 (4)
Responses <same as request> (4)
Any IGP 0010 (maximize reliability)
EGP 0000
SNMP 0010 (maximize reliability)
BOOTP 0000
Notes:
(1) Includes all interactive user protocols (e.g., rlogin).
(2) Includes all bulk data transfer protocols (e.g., rcp).
(3) If the implementation does not support changing the TOS during
the lifetime of the connection, then the recommended TOS on
opening the connection is the default TOS (0000).
(4) Although ICMP request messages are normally sent with the
default TOS, there are sometimes good reasons why they would be
sent with some other TOS value. An ICMP response always uses the
same TOS value as was used in the corresponding ICMP request
message.An application may (at the request of the user) substitute 0001 (minimize monetary cost) for any of the above values.

RFC 1340 Assigned Numbers July 1992
IP TIME TO LIVE PARAMETERThe current recommended default time to live (TTL) for the Internet Protocol (IP) [[45](#ref-45 ""DDN Protocol Handbook""),[105](#ref-105 ""Internet Protocol - DARPA Internet Program Protocol Specification"")] is 64.

NETWORK MANAGEMENT PARAMETERSFor the management of hosts and gateways on the Internet a data structure for the information has been defined. This data structure should be used with any of several possible management protocols, such as the "Simple Network Management Protocol" (SNMP) RFC-1157 [[15](#ref-15 ""A Simple Network Management Protocol"")], or the "Common Management Information Protocol over TCP" (CMOT) [[142](#ref-142 ""The Common Management Information Services and Protocol over TCP/IP (CMOT)"")].
The data structure is the "Structure and Indentification of Management Information for TCP/IP-based Internets" (SMI) RFC-1155 [[120](#ref-120 ""Structure and Identification of Management Information for TCP/IP-based internets"")], and the "Management Information Base for Network Management of TCP/IP-based Internets" (MIB-II) [[121](#ref-121 ""Management Information Base for Network Management of TCP/IP-based internets: MIB-II"")].
The SMI includes the provision for panrameters or codes to indicate experimental or private data structures. These parameter assignments are listed here.
The older "Simple Gateway Monitoring Protocol" (SGMP) RFC-1028 [[37](#ref-37 ""A Simple Gateway Monitoring Protocol"")] also defined a data structure. The parameter assignments used with SGMP are included here for hist orical completeness.
The network management object identifiers are under the iso (1), org (3), dod (6), internet (1), or 1.3.6.1, branch of the name space.

MILNET LOGICAL ADDRESSESThe MILNET facility for "logical addressing" is described in RFC-878 [[57](#ref-57 ""Telnet Terminal Speed Option"")] and RFC-1005 [[109](#ref-109 ""Telnet Extended Options - List Option"")]. 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 the IANA. Assignments for other logical host addresses are made by the NIC.

MILNET LINK NUMBERSThe word "link" here refers to a field in the original MILNET 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](#ref-2 ""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.

RFC 1340 Assigned Numbers July 1992
MILNET X.25 ADDRESS MAPPINGSAll MILNET hosts are assigned addresses by the Defense Data Network (DDN). The address of a MILNET host may be obtained from the Network Information Center (NIC), represented as an ASCII text string in what is called "host table format". This section describes the process by which MILNET X.25 addresses may be derived from addresses in the NIC host table format.
A NIC host table address consists of the ASCII text string representations of four decimal numbers separated by periods, corresponding to the four octeted of a thirty-two bit Internet address. The four decimal numbers are referred to in this section as "n", "h' "l", and "i". Thus, a host table address may be represented as: "n.h.l.i". Each of these four numbers will have either one, two, or three decimal digits and will never have a value greater than 255. For example, in the host table, address: "10.2.0.124", n=10, h=2, l=0, and i=124. To convert a host table address to a MILNET X.25 address:
1. If h < 64, the host table address corresponds to the X.25
physical address:
ZZZZ F IIIHHZZ (SS)
where:
ZZZZ = 0000 as required
F = 0 because the address is a physical address;
III is a three decimal digit respresentation of
"i", right-adjusted and padded with leading
zeros if required;
HH is a two decimal digit representation of "h",
right-adjusted and padded with leading zeros
if required;
ZZ = 00 and
(SS) is optional
In the example given above, the host table address 10.2.0.124
corresponds to the X.25 physical address 000001240200.Reynolds & Postel [Page 51]
RFC 1340 Assigned Numbers July 1992
If h > 64 or h = 64, the host table address corresponds to the X.25 logical address
ZZZZ F RRRRRZZ (SS)
where:
ZZZZ = 0000 as required
F = 1 because the address is a logical address;
RRRRR is a five decimal digit representation of
the result "r" of the calculation
r = h * 256 + i
(Note that the decimal representation of
"r" will always require five digits);
ZZ = 00 and
(SS) is optional
Thus, the host table address 10.83.0.207 corresponds to the X.25
logical address 000012145500.In both cases, the "n" and "l" fields of the host table address are not used.

RFC 1340 Assigned Numbers July 1992
IEEE 802 NUMBERS OF INTERESTSome 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 MILNET 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 (such as the Address Resolution Protocol (ARP)) on 802 networks was developed, using the SNAP extension (see RFC-1042 [[90](#ref-90 ""A Standard for the Transmission of IP Datagrams over IEEE 802 Networks"")]).

ETHERNET NUMBERS OF INTERESTMany 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.
If you need an Ethernet type, contact the Xerox Corporation, Xerox Systems Institute, 475 Oakmead Parkway, Sunnyvale, CA 94086, Attn: Ms. Fonda Pallone, (415) 813-7164.

RFC 1340 Assigned Numbers July 1992
ETHERNET VENDOR ADDRESS COMPONENTSEthernet hardware addresses are 48 bits, expressed as 12 hexadecimal digits (0-9, plus A-F, capitalized). These 12 hex digits consist of the first/left 6 digits (which should match the vendor of the Ethernet interface within the station) and the last/right 6 digits which specify the interface serial number for that interface vendor.
Ethernet addresses might be written unhyphenated (e.g., 123456789ABC), or with one hyphen (e.g., 123456-789ABC), but should be written hyphenated by octets (e.g., 12-34-56-78-9A-BC).
These addresses are physical station addresses, not multicast nor broadcast, so the second hex digit (reading from the left) will be even, not odd.
At present, it is not clear how the IEEE assigns Ethernet block addresses. Whether in blocks of 224 or 225, and whether multicasts are assigned with that block or separately. A portion of the vendor block address is reportedly assigned serially, with the other portion intentionally assigned randomly. If there is a global algorithm for which addresses are designated to be physical (in a chipset) versus logical (assigned in software), or globally-assigned versus locally-assigned addresses, some of the known addresses do not follow the scheme (e.g., AA0003; 02xxxx).

Protocol field values in the "0---" to "3---" range identify the network-layer protocol of specific datagrams, and values in the "8-- -" to "b---" range identify datagrams belonging to the associated Network Control Protocol (NCP), if any.
It is recommended that values in the "02--" to "1e--" and "--01" to "--1f" ranges not be assigned, as they are compression inefficient.
Protocol field values in the "4---" to "7---" range are used for protocols with low volume traffic which have no associated NCP.
Protocol field values in the "c---" to "e---" range identify datagrams as Control Protocols (such as LCP).
