   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 for duplex, bidirectional traffic. They usually
   use port numbers that match the services 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. 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.

              available for assignment upon request to IANA.^[3]              

Well-known ports[edit]

   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 2^10 − 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[edit]

    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. Subsequntly, 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.
