  "whatItIs": "IANA lists 280 as http-mgmt, assigned to Adrian Pell, but no protocol document was ever published for it and no widely deployed product claims the name. What actually turns up on 280 is ordinary HTTP: a device or appliance whose web management interface was moved off 80, or a proxy or admin console picking a low free port. Treat it as unidentified HTTP and confirm with a request rather than assuming the registration describes the listener.",
