ConMet — 4 prefixes (MA-L)

A MAC address beginning with D0:98:9C, 14:5B:B9, 34:EE:2A, or 54:66:F9 belongs to ConMet (Consolidated Metco), a commercial-vehicle components manufacturer, typically seen on industrial fleet/OEM embedded electronics rather than consumer network gear.

ConMet is a substantial, identifiable company, not a bare single-OUI registration. It holds four separate IEEE MA-L assignments under the identical name and Vancouver, WA address, consistent with an active manufacturer that has needed repeated MAC-address block allocation over time. Founded in 1964 and owned by Amsted Industries, the company operates 16 global manufacturing facilities and maintains a detailed corporate website.

ConMet's traditional product lines — PreSet and PreSet Plus wheel hubs, brake drums, castings, and TruckWings aerodynamic fairings — are mechanical components with no obvious network interface. The company also markets an eHub/eMobility electric wheel-hub power-unit line for trailer refrigeration and electrified trucks, integrated with Carrier Transicold and Freightliner eCascadia, which is a plausible source of embedded MAC-bearing hardware, but no product documentation confirms which specific device carries these OUIs.

No FCC ID filings under ConMet or Consolidated Metco were found, and no CVEs or security advisories reference the company. A similarly-named "Wheel Hub Data Sensor" (FCC ID 2AY6OSHN01) belongs to a distinct company, Rivata Inc., with no confirmed relationship to ConMet.

Analyst note

Four independent MA-L assignments to the identical name/address is stronger evidence of an active industrial-electronics vendor than a bare single-OUI shell, but no product documentation confirms which ConMet hardware line carries these MACs — treat device attribution as fleet/OEM embedded electronics context, not consumer IoT, until a specific product is documented.
