ASSIGNED NUMBERS
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 Jon Postel. The assignment of
numbers is also handled by Jon. If you are developing a protocol or
application that will require the use of a link, socket, port, protocol,
or network number please contact Jon to receive a number assignment.

Most of the protocols mentioned here are documented in the RFC series of
notes. The more prominent and more generally used are documented in the
Protocol Handbook [17] prepared by the Network Information Center (NIC).
Some of the items listed are undocumented. In all cases the name and
mailbox of the responsible individual is indicated. In the lists that
follow, a bracketed entry, e.g., [17,iii], at the right hand margin of
the page indicates a reference for the listed protocol, where the number
cites the document and the "iii" cites the person.

ASSIGNED NETWORK NUMBERS
This list of network numbers is used in the internet address [33].
The Internet Protocol (IP) uses a 32 bit address 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, or class a, of address has a 7-bit network number
and a 24-bit local address. This allows 128 class a networks.

The second type, or class b, of address has a 14-bit network
number and a 16-bit local address. This allows 16,384 class b
networks.

The third type, or class c, of address has a 21-bit network number
and a 8-bit local address. This allows 2,097,152 class c
networks.

Class C Address
One notation for internet host addresses commonly used 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. For
example, the internet address of ISIF is 010.020.000.052.
This notation will be used in the listing of assigned network

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 or rest
field.

Assigned Numbers
Port or Socket Numbers
ASSIGNED PORT or SOCKET NUMBERS
Ports are used in the TCP [34] and sockets are used in the AHHP
[28,17] to name the ends of logical connections which carry long term
conversations. For the purpose of providing services to unknown
callers a service contact socket is defined. This list specifies the
port or socket used by the server process as its contact socket. In
the AHHP an Initial Connection Procedure ICP [39,17] is used between
the user process and the server process to make the initial contact
and establish the long term connections leaving the contact socket
free to handle other callers. In the TCP no ICP is necessary since a
port may engage in many simultaneous connections.
To the extent possible these same port assignments are used with UDP
[42].
The assigned ports/sockets use a small part of the possible
port/socket numbers. The assigned ports/sockets have all except the
low order eight bits cleared to zero. The low order eight bits are
specified here.

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. Some time after the ARPANET Host-to-Host (AHHP) protocol
was defined and, by now, some time ago the definition of this field
was changed to "Message-ID" and the length to 12 bits. The name link
now refers to the high order 8 bits of this 12 bit message-id field.
The low order 4 bits of the message-id field are to be zero unless
specifically specified otherwise for the particular protocol used on
that link. The Host/IMP interface is defined in BBN report 1822 [1].
