Port Number List
A port number uniquely identifies a network-based application on a computer. This number is assigned automatically by the OS, manually by the user, or is set as a default for some popular applications
The port numbers are divided into three ranges: the well-known ports, the registered ports, and the dynamic or private ports. The registered ports are those from 1024 through 49151. IANA maintains an official list of well-known and registered ranges. The dynamic or private ports are those from 49152 through 65535.
