Port 8881

Port 8881 is often used for alternative HTTP traffic. Specifically, it may be used by the Plesk control panel software to allow users to access web servers and other hosted applications via an alternative port. It is sometimes referred to as a “secure” port, though this may be misleading as it does not necessarily offer any greater security than other ports used for HTTP traffic. Ultimately, the specific use of this port will depend on the software and applications being run on a given server.

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.
