This is a list of [[Internet socket]] [[port number]]s used by protocols of the [[Transport Layer]] of the [[Internet Protocol Suite]] for the establishment of host-to-host communications.

Originally, these port numbers were used by the [[Transmission Control Protocol]] (TCP) and the [[User Datagram Protocol]] (UDP), but are used also for the [[Stream Control Transmission Protocol]] (SCTP), and the [[Datagram Congestion Control Protocol]] (DCCP). SCTP and DCCP services usually use a port number that matches the service of the corresponding TCP or UDP implementation if they exist.
The [[Internet Assigned Numbers Authority]] (IANA) is responsible for maintaining the official assignments of port numbers for specific uses.<ref name=IANA>
{{cite web
| url = http://www.iana.org/assignments/port-numbers
| title = Port Numbers
| publisher = The Internet Assigned Numbers Authority (IANA)
| date = 2011-07-11
}}
</ref> However, many unofficial uses of both well-known and registered port numbers occur in practice.

== Table legend ==

|- style="background:#f9f9f9;" <!-- light grey -->

| Unofficial || Port is not registered with IANA for the application &nbsp; || blue
|- style="background:khaki;" <!-- khaki -->
| Multiple use || Multiple applications are known to use this port. || yellow
|}

== Well-known ports ==<!--[[Well-known ports]] and similar redirect here-->
The port numbers in the range from 0 to 1023 are the ''well-known ports''. They are used by system processes that provide widely-used types of network services. On [[Unix-like]] operating systems, a process must execute with [[superuser]] privileges to be able to bind a network [[network socket|socket]] to an [[IP address]] using one of the well-known ports.

<!-- In this table, the Port number, TCP and UDP columns are lined up
using spaces as padding. The reason for this is for wiki markup readability only.
It does not affect the browser rendering of the page. -->

== Registered ports ==
{{External links|date=October 2011}}
The range of port numbers from 1024 to 49151 are the registered ports. They are assigned by IANA for specific service upon application by a requesting entity.<ref name=IANA /> On most systems registered ports can be used by ordinary users.

This is an '''incomplete list''' of notable ports. See the [http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xml official IANA list] for the complete list of IANA assigned ports.

<!-- In this table, the Port number, TCP and UDP columns are lined up
using spaces as padding. This is for wiki markup readability only.
It does not affect the browser rendering of the page. -->

Revision as of 10:09, 10 February 2012

This is a list of Internet socket port numbers used by protocols of the Transport Layer of the Internet Protocol Suite for the establishment of host-to-host communications.

Originally, these port numbers were used by the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP), but are used also for the Stream Control Transmission Protocol (SCTP), and the Datagram Congestion Control Protocol (DCCP). SCTP and DCCP services usually use a port number that matches the service of the corresponding TCP or UDP implementation if they exist. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses.[1] However, many unofficial uses of both well-known and registered port numbers occur in practice.

Table legend

Use Description Color
Official Port is registered with IANA for the application white
Unofficial Port is not registered with IANA for the application   blue
Multiple use Multiple applications are known to use this port. yellow

Well-known ports

The port numbers in the range from 0 to 1023 are the well-known ports. They are used by system processes that provide widely-used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the well-known ports.
