The port numbers are divided into three ranges: the Well Known Ports, the Registered Ports, and the 

Dynamic and/or Private Ports. The Well Known Ports are those from 0 through 1023. The Registered 

Ports are those from 1024 through 49151.  The Dynamic and/or Private Ports are those from 49152 

through 65535. 

The Well Known Ports are assigned by the IANA, and on most systems, can only be used by system 

processes or by programs executed by privileged users.  Table B-1 shows famous port numbers 

among the well-known port numbers. For more details, please visit IANA website:
