Port 8000 TCP
According to the official RFC/Specification for network port allocations port TCP/8000 is allocated to Intel.com for use by their iRDMI (Intel Remote Desktop Management Interface) protocol, however in reality this protocol is not very wildly used in modern day networks.
Instead, the most common use for TCP/8000 is an alternative port number for HTTPs or HTTP. Typically you may find people using this port when another service is already bound to port 80, such as a web server, or people are trying to use an alternative port as a crude security mechanisim.
