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:
