TCP/UDP Port Numbers
Port numbers are divided into three ranges: Well Known Ports (0 through 1023), Registered Ports (1024
through 49151), and Dynamic and/or Private Ports (49152 through 65535).
Well Known Ports are assigned by IANA, and on most systems can only be used by system processes or
programs executed by privileged users. The table below lists some of the well-known port numbers. For
more details, please visit the IANA website: http://www.iana.org/assignments/port-numbers
