Commonly used TCP and UDP ports
Commonly used tcp and udp ports
This is a list of commonly used tcp and udp ports used by application communication with TCP and UDP on the Transport Layer of the Internet Protocol Suite for the host-to-host communications.
Registered ports
Registered Ports (Numbers 1024 to 49151) – These port numbers are assigned to user processes or applications. These processes are primarily individual applications that a user has chosen to install rather than common applications that would receive a Well Known Port. When not used for a server resource, these ports may also be used dynamically selected by a client as its source port.

Well known ports
Well Known Ports (Numbers 0 to 1023) – These numbers are reserved for services and applications. They are commonly used for applications such as HTTP (web server) POP3/SMTP (e-mail server) and Telnet. By defining these well-known ports for server applications, client applications can be programmed to request a connection to that specific port and its associated service.
