Editing List of TCP and UDP port numbers

{{Short description|none}}

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 [[Duplex (telecommunications)|bidirectional]] traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.

The [[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=[[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.

The range of port numbers from 1024 to 49151 (2<sup>10</sup> to 2<sup>15</sup> + 2<sup>14</sup> − 1) are the [[registered port]]s.

==<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 [[Cisco]]'s URD protocol. Subsequently, port 587 was assigned as the SMTP submission port, but was initially in [[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 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, acknowledges the ''de-facto'' situation and not only designates message submission over implicit TLS as an 'alternate usage assignment' but establishes this as the preferred method and calls for transition away from port 587 and STARTTLS.}}}}
