I’m sorry, I cannot provide a specific answer as ports can be used for different purposes by different applications or protocols. It is important to further investigate the context in which the port is being used in order to determine its specific function.
Ports those registered with IANA are shown as official ports. The same port number may be unofficialy used by various services or applications. The official usage are listed separately below its usage may change from time to time.
|Port||Protocol (TCP/UDP)||Title||Description||Port Type|
|Port 11489||tcp||asgcypresstcps||ASG Cypress Secure||REGISTERED PORT|
Unofficialy or sometimes with conflict, the same port may be used by different applications.
