View source for List of TCP and UDP port numbers

{{Short description|Well-known Port Numbers used in TCP and UDP communications on computer networks}}
This is a '''list of TCP and UDP port numbers''' used by protocols for operation of network applications.
The [[Transmission Control Protocol]] (TCP) and the [[User Datagram Protocol]] (UDP) only need one [[Port (computer networking)|port]] for [[Engineering:Duplex (telecommunications)|duplex]], bidirectional traffic. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist.

The [[Organization:Internet Assigned Numbers Authority|Internet Assigned Numbers Authority]] (IANA) is responsible for maintaining the official assignments of port numbers for specific uses.<ref>{{cite web |title=Service Name and Transport Protocol Port Number Registry |url=https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xml |access-date=8 October 2023 |website=[[Organization:Internet Assigned Numbers Authority|Internet Assigned Numbers Authority]]}}</ref> However, many unofficial uses of both well-known and registered port numbers occur in practice. Similarly, many of the official assignments refer to protocols that were never or are no longer in common use. This article lists port numbers and their associated protocols that have experienced significant uptake.

==Registered ports==
<!-- Registered ports and similar redirect here. -->
{{Dynamic list}}

The range of port numbers from 1024 to 49151 (2<sup>10</sup> to 2<sup>14</sup> + 2<sup>15</sup> − 1) are the [[Registered port|registered port]]s. They are assigned by [[Organization:Internet Assigned Numbers Authority|IANA]] for specific service upon application by a requesting entity.<ref name="IANA" /> On most systems, registered ports can be used without superuser privileges.

<!-- In this table, the Port number, TCP and UDP columns are lined up
     using spaces as padding. This is for wiki markup readability only.

==<span lang="vi" dir="ltr">Note</span>==
{{NoteFoot|refs=
{{NoteTag|name=tcp465|TCP port 465 was originally assigned to allow the use of [[Simple Mail Transfer Protocol|SMTP]] over [[Transport Layer Security|SSL]] ([[SMTPS]]), but practical concerns meant that it was left unused and according to the registration rules at that time was subsequently revoked and eventually re-assigned for use by [[Company:Cisco|Cisco]]'s URD protocol. Subsequently, port 587 was assigned as the SMTP submission port, but was initially in [[Plaintext|plaintext]], with encryption eventually provided years later by the STARTTLS extension. At the same time, the subsequent adoption of the usage of 465 as an SSL-enabled SMTP submission port, even though that the original registration did not envision that usage and despite the fact that it was registered to another service has endured. Subsequently, RFC 8314, in a special exemption to the normal assignment process as defined by RFC 6335, has acknowledged the ''de-facto'' situation and has designated SMTP over TLS as an 'alternate usage assignment'.}}}}
