Well-known TCP/UDP Port Numbers
Port numbers are divided into three ranges: Well Known Ports, Registered Ports, and Dynamic and/or Private Ports. Well-known ports
are those from 0 through 1023. Registered Ports are those from 1024 through 49151. Dynamic and/or Private Ports are those from 49152
through 65535.
Well-known ports are assigned by IANA, and on most systems, can only be used by system processes or by programs executed by
privileged users. Table below shows some of the well-known port numbers. For more details, please visit the IANA website:
