Ford Motor Company — 3 prefixes (MA-L)

Ford Motor Company (NYSE: F), the Dearborn, Michigan automaker, holds at least two IEEE MA-L blocks under the exact registrant name "Ford Motor Company" — 00:26:B4 and 00:76:B6, both tied to the 20300 Rotunda Drive HQ address. A third block, 5C:5A:EA, is registered under the shortened name "FORD" at 17425 Federal Drive, Allen Park, MI — the address of Ford's Research & Innovation Center — and is very likely the same corporate entity, though the registry string differs enough that it is flagged rather than merged outright. A fourth, unrelated historic block, 00:00:45 "FORD AEROSPACE & COMM. CORP.," is excluded from this entry: that division was divested from Ford in 1990 and became part of Loral, later Lockheed Martin, making it a distinct legal entity rather than the modern automaker. Device-level corroboration is thinner than the company-identity signal: owner forum threads that name specific Ford-vehicle MAC vendors actually trace to tier-1 suppliers' own OUIs (e.g., Flextronics 28:38:5C for SYNC hardware, Qualcomm 78:55:CD for the telematics modem), not to Ford's own registered blocks, so exactly what hardware broadcasts from 00:26:B4/00:76:B6/5C:5A:EA in the field is inferred, not directly observed.

MA-L 5C

5A:EA → registrant "FORD" (short form), 17425 Federal Drive, Allen Park, MI 48101, US — matches Ford's Research & Innovation Center; likely the same company but the org-name string is not an exact match to "Ford Motor Company"

Excluded block

MA-L 00:00:45 → "FORD AEROSPACE & COMM. CORP.," Colorado Springs, CO — divested from Ford in 1990 (became Loral, later Lockheed Martin); a separate legal entity, not merged into this vendor [Confirmed] — https://standards-oui.ieee.org/oui/oui.csv

Registration/assignment dates

not published by IEEE for any of these rows; third-party "updated" timestamps (e.g. maclookup.app) are database-scrape artifacts of when that vendor's row was last touched in their own database, not an IEEE assignment date, and are not recorded here

Device/product context

vehicle network hardware, in-vehicle SYNC infotainment, "Ford Telematics" fleet-connectivity service (launched 2020); specific device-to-MAC mappings found in owner forums actually cite Ford's tier-1 suppliers' OUIs (Flextronics 28:38:5C, Qualcomm 78:55:CD), not Ford's own blocks directly
