TIdUDPClient.Port Property

Identifies the port number on the remote system.

property Port;

Port is an Integer property used to identify the port number on the remote computer system in Host

Host and Port are used to build the UDP datagram, and identify the endpoint for the transmission. 

Some UDP-based protocols, such as SNTP (Simple Network Time Protocol) and DNS, used pre-defined port numbers. Port numbers below 1024 are reserved, but using a number above 1024 does not guarantee there will be no conflict.
