  "whatItIs": "IANA lists 8766 on TCP and UDP as amcs, the Agilent Connectivity Service. It belongs to Agilent's instrument-control software stack, so it shows up on scientific and manufacturing workstations that talk to lab hardware. Outside that niche the port has no common squatter, and a listener on a general-purpose server is worth identifying by process rather than by the registry name.",
