Port

Legend of TCP and UDP protocol table cells for port numbers

CellDescription
YesDescribed protocol is assigned by IANA for this port, and is: standardized, specified, or widely used for such.
UnofficialDescribed protocol is not assigned by IANA for this port, but is: standardized, specified, or widely used for such.
AssignedDescribed protocol is assigned by IANA for this port,[2] but is not: standardized, specified, or widely used for such.
NoDescribed protocol is not: assigned by IANA for this port, standardized, specified, or widely used for such.
ReservedPort is reserved by IANA,[2] generally to prevent collision having its previous use removed.[3][4] The port number may be available for assignment upon request to IANA.[3]

Well-known ports

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.

The port numbers in the range from 0 to 1023 (0 to 210 − 1) are the well-known ports or system ports.[3] 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.[5]

Note

  1. ^ TCP port 465 was originally assigned to allow the use of SMTP over 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 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'.
  2. ^ Deployment typically occurs only directly over UDP, but other underlying protocol layers which meet the requirements described in the specification are possible.
