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].
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.

RFC 1340 Assigned Numbers July 1992
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]. 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 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
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 1340 Assigned Numbers July 1992
Special Addresses:
There are five classes of IP addresses: Class A through Class E
[119]. 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]. 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.

WELL KNOWN PORT NUMBERS
The 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 [45,106] 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 [46,104].
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 NUMBERS
The 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 [45,106] 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 [46,104].
The Registered Ports are in the range 1024-65535.
Port Assignments:

low-order bits of the IP Multicast address are placed in the low-
order 23 bits of the Ethernet or IEEE 802 net multicast address
Reynolds & Postel [Page 27]
RFC 1340 Assigned Numbers July 1992
1.0.94.0.0.0. See the next section on "IANA ETHERNET ADDRESS
BLOCK".
Reynolds & Postel [Page 28]
RFC 1340 Assigned Numbers July 1992
IANA ETHERNET ADDRESS BLOCK
The 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 1010
In 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 uses
Appearance 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 uses
The 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 decimal
Reynolds & Postel [Page 29]
RFC 1340 Assigned Numbers July 1992
IP TOS PARAMETERS
This 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.
Reynolds & Postel [Page 31]
RFC 1340 Assigned Numbers July 1992
IP TIME TO LIVE PARAMETER
The current recommended default time to live (TTL) for the Internet
Protocol (IP) [45,105] is 64.
Reynolds & Postel [Page 32]
RFC 1340 Assigned Numbers July 1992
DOMAIN SYSTEM PARAMETERS

NETWORK MANAGEMENT PARAMETERS
For 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], or
the "Common Management Information Protocol over TCP" (CMOT) [142].
The data structure is the "Structure and Indentification of Management
Information for TCP/IP-based Internets" (SMI) RFC-1155 [120], and the
"Management Information Base for Network Management of TCP/IP-based
Internets" (MIB-II) [121].
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]
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 ADDRESSES
The MILNET facility for "logical addressing" is described in RFC-878
[57] and RFC-1005 [109]. 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 NUMBERS
The 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].
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 MAPPINGS
All 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
2. 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.
Reynolds & Postel [Page 52]
RFC 1340 Assigned Numbers July 1992
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 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]).

ETHERNET NUMBERS OF INTEREST
Many 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

RFC 1340 Assigned Numbers July 1992
ETHERNET VENDOR ADDRESS COMPONENTS
Ethernet 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 2**24 or 2**25, 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).

PRONET 80 TYPE NUMBERS
Below is the current list of PRONET 80 Type Numbers. Note: a
protocol that is on this list does not necessarily mean that there is
any implementation of it on ProNET.
Of these, protocols 1, 14, and 20 are the only ones that have ever
been seen in ARP packets.
For reference, the header is (one byte/line):
destination hardware address
source hardware address
data link header version (2)
data link header protocol number
data link header reserved (0)
data link header reserved (0)
Some protocols have been known to tuck stuff in the reserved fields.
Those who need a protocol number on ProNET-10/80 should contact John
Shriver (jas@proteon.com).
