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 that are numbered from 0 to 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. The table below shows some of the
well-known port numbers. For more details, please visit the IANA website:
