List of TCP and UDP port numbers.This is a list of notable port numbers used by protocols of the transport layer of the Internet protocol suite for the establishment of host to host connectivity.Originally, port numbers were used by the Network Control Program NCP in the ARPANET for which two ports were required for half duplex transmission.Later, the Transmission Control Protocol TCP and the User Datagram Protocol UDP needed only one port for full duplex, bidirectional traffic.The even numbered ports were not used, and this resulted in some even numbers in the well known port number range being unassigned.The Stream Control Transmission Protocol SCTP and the Datagram Congestion Control Protocol DCCP also use port numbers.This is a list of notable port numbers used by protocols of the transport layer of the Internet protocol suite for the establishment of hosttohost connectivity.CVE version 20061101 and Candidates as of 20171031 Candidates must be reviewed and accepted by the CVE Editorial Board before they can be added to the official CVE.List of the most recent changes to the free Nmap Security Scanner.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.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.Flexlm Error 15 Cannot Connect To License Server Communication' title='Flexlm Error 15 Cannot Connect To License Server Communication' />Table legendedit Official Port is registered with IANA for the application.Unofficial Port is not registered with IANA for the application.Multiple use Multiple applications are known to use this port.Well known portseditThe port numbers in the range from 0 to 1.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.Well known ports.Port.
