Xerox holds about 14 IEEE blocks (MA-L and MA-M) registered as "XEROX CORPORATION" at 800 Phillips Rd, Webster, NY (the Webster/Rochester area). Verified samples include the historic 00:00:00 through 00:00:09 block range (among the very first IEEE assignments ever made), plus 00:00:AA, 9C:93:4E, C0:FB:F9:0 (MA-M), and E8:4D:EC. These OUIs appear on laser printers, multifunction printers (MFPs), production printing systems, and office equipment. Unlike the ODMs and chipset makers in this batch, a Xerox OUI maps to the Xerox brand — network MFPs are common, durable enterprise assets. Two important nuances: Xerox holds the historic 00:00:00 block, and because 00:00:00 is sometimes used as a placeholder or null MAC, the full address must be validated before classifying a device as Xerox; and the former Fuji Xerox joint venture ended in 2021 and became Fujifilm Business Innovation — a separate entity with its own OUIs. As of 1 July 2025, Xerox also owns Lexmark (which keeps its own OUIs/branding). For triage, a Xerox OUI means a Xerox-brand network printer or MFP, but validate the full address since 00:00:00 can appear as a null MAC.

- Special note
- Xerox holds the historic 00:00:00 block (among the very first IEEE assignments); because 00:00:00 is sometimes used as a placeholder/null MAC, validate the full address before classifying a device as Xerox. The former Fuji Xerox JV ended in 2021 and became Fujifilm Business Innovation — a SEPARATE entity with its own OUIs. Xerox also rebadges some third-party print engines. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]

- Analyst note
- A Xerox OUI = a Xerox-brand network printer/MFP; note 00:00:00 is sometimes used as a placeholder/null MAC, so validate the full address before classifying a device as Xerox.
