Port 27

Modified by:

Port 27 is not a well-known port and is not assigned any specific use or service. It is typically unassigned and available for use by any application or service that requires a communication channel. However, some older sources indicate that it may have been used for the “NSW User System FE” protocol, which was a part of the obsolete X.25 packet switching protocol used for communication in outmoded computer networks.

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.
