Ingeteam — 2 prefixes (MA-L)

Ingeteam holds two MA-L (24-bit OUI) blocks, 00:0D:A9 and 00:16:A3, both registered to "INGETEAM" at Parque Tecnologico de Bizkaia, Edificio 110, Zamudio, Bizkaia 48170, Spain — the company's home in the Basque Country. Founded in 1972, Ingeteam is a Spanish electrical-technology group of more than 4,000 employees across roughly 15 countries, specialising in rotating machines, power electronics, and industrial control and automation. For network-asset work the salient point is that these prefixes mark industrial OT/ICS hardware: programmable controllers and RTUs (the INGESYS IC2 line), SCADA and HMI platforms (INGESYS IT, INGESYS SMART SCADA), power converters and inverters, and EV chargers. That equipment is deployed in critical-infrastructure sectors — wind, photovoltaic, hydroelectric, battery storage, smart grids and substation automation, railway traction, marine, and metals — so a MAC carrying one of these OUIs on a corporate LAN is a signal that grid/energy/rail OT gear is present and, outside an expected OT segment, warrants scrutiny. No Ingeteam-specific CISA ICS advisory or CVE surfaced in this pass; absence of a public CVE is not evidence of safety for network-attached OT devices. IEEE publishes no OUI assignment dates, so any "date registered" shown by lookup services (e.g. 2003-06-30 for 00:0D:A9) is a third-party database artifact, not an IEEE fact, and is not recorded here.

MAM / OUI-36 match

Allocated date

Unknown — IEEE publishes no registration dates for MA-L/OUI assignments; none present in the cached registry CSV. Lookup-tool dates (e.g. 2003-06-30, 2005-11-29) are third-party artifacts, not recorded. [Unknown] — IEEE standards.ieee.org/products-programs/regauth

Known CVEs / advisories

Unknown — no Ingeteam-specific CISA ICS advisory or CVE surfaced in this pass [Unknown] — cisa.gov/news-events/ics-advisories

Analyst note

These OUIs identify industrial OT/ICS equipment (controllers, RTUs, SCADA, converters, EV chargers). Expected only in OT-segment / energy-grid-rail-marine environments; a MAC with one of these prefixes outside such a segment merits investigation. INGESYS SMART SCADA markets "strictest cybersecurity requirements" but names no specific IEC 62443 / NERC CIP certification.
