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 "Official Internet
Protocols" [118]. The more prominent and more generally used are
documented in the "DDN Protocol Handbook, Volume Two, DARPA Internet
Protocols" [45] prepared by the NIC. Other collections of older or
obsolete protocols are contained in the "Internet Protocol Transition
Workbook" [76], or in the "ARPANET Protocol Transition Handbook"
[47]. For further information on ordering the complete 1985 DDN
Protocol Handbook, write: SRI International (SRI-NIC), DDN Network
Information Center, Room EJ291, 333 Ravenswood Avenue, Menlo Park,
CA., 94025; or call: 1-800-235-3155. Also, the Internet Activities
Board (IAB) publishes the "IAB Official Protocol Standards" [62],
which describes the state of standardization of protocols used in the
Internet. This document is issued quarterly. Current copies may be
obtained from the DDN Network Information Center or from the IANA.
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]. 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.
Special Addresses:
There are five classes of IP addresses: Class A through Class E
[119]. Of these, Class D and Class E addresses are reserved for
experimental use. A gateway which is not participating in these
experiments must ignore all datagrams with a Class D or 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.
(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.
VERSION NUMBERS
In the Internet Protocol (IP) [45,105] there is a field to identify
the version of the internetwork general protocol. This field is 4
bits in size.

PORT NUMBERS
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].
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.

INTERNET MULTICAST ADDRESSES
Host Extensions for IP Multicasting (RFC-1112) [43] specifies the
extensions required of a host implementation of the Internet Protocol
(IP) to support multicasting. Current addresses are listed below.
224.0.0.0 Reserved [43,JBP]
224.0.0.1 All Hosts on this Subnet [43,JBP]
224.0.0.2 All Gateways on this Subnet (proposed) [JBP]
224.0.0.3 Unassigned [JBP]
224.0.0.4 DVMRP Routers [140,JBP]
224.0.0.5 OSPFIGP OSPFIGP All Routers [83,JXM1]
224.0.0.6 OSPFIGP OSPFIGP Designated Routers [83,JXM1]
244.0.0.7-244.0.0.255 Unassigned [JBP]
224.0.1.0 VMTP Managers Group [17,DRC3]
224.0.1.1 NTP Network Time Protocol [80,DLM1]
224.0.1.2 SGI-Dogfight [AXC]
224.0.1.3 Rwhod [SXD]
224.0.1.4 VNP [DRC3]
244.0.1.5-244.0.1.255 Unassigned [JBP]
224.0.2.1 "rwho" Group (BSD) (unofficial) [JBP]
232.x.x.x VMTP transient groups [17,DRC3]
Note that when used on an Ethernet or IEEE 802 network, the 23
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
1.0.94.0.0.0. See the next section on "IANA ETHERNET ADDRESS
BLOCK".
