Racal-Datacom, LAN Internetworking Division — 3 prefixes (MA-L)

A MAC address beginning with 00:07:01, 02:07:01, or 02:70:01 belongs to Racal-Datacom's LAN Internetworking Division, registered at Boxborough, Massachusetts. All three IEEE MA-L prefixes trace to the same registrant address, and the devices carrying them are Ethernet network interface cards, adapters, hubs, and routers built for LAN internetworking hardware from the late 1980s through the 1990s.

The Boxborough, MA address links this registration to Racal-Interlan, an Ethernet-adapter maker that Racal acquired in 1989 for $57 million. Racal-Datacom itself descends from Milgo Electronic Corporation, a data-communications vendor founded in 1955 and later rebranded Racal-Milgo, known for modems, multiplexers, routers, and LAN hubs.

Racal-Datacom remained an active data-communications supplier into the 1990s, including a 1996 UK Ministry of Defence networking contract and a 1992 partnership with BellSouth. No CVEs or vulnerability advisories were found for Racal-Datacom or Racal-Interlan products, though this is consistent with legacy hardware that predates CVE tracking rather than a confirmed clean record.

Three separate OUI assignments to the same registrant, corroborated by documented acquisition history and product lines, place this entry above the bare single-OUI shell threshold — it identifies a real company with verifiable device context, not just an isolated IEEE registration.

IEEE assignment

3 prefixes (00:07:01, 02:07:01, 02:70:01) → RACAL-DATACOM, LAN INTERNETWORKING DIVISION, registered Boxborough, MA, US [Confirmed] — the IEEE MA-L registry

Registry / block size

MA-L (48-bit OUI); 3 IEEE prefixes to this registrant, each a standard 24-bit block [Confirmed] — the IEEE MA-L registry. Search also covered the IEEE MA-M registry and the IEEE MA-S registry with no additional matches [Confirmed] — the IEEE MA-M registry, the IEEE MA-S registry

Analyst note

A Racal-Datacom OUI reliably identifies legacy Ethernet/LAN internetworking hardware from the Boxborough, MA division; no current-day product line exists under this name, so treat matches as historic infrastructure, not live shipping hardware [Likely]
