OKI — ~4 prefixes (MA-L); printer/office/telecom, OUI = brand
Summary
- // what this is
- Oki Electric Industry is registered to MAC prefix
00:80:87and 3 more in the IEEE OUI database. When a device's MAC address begins with00:80:87, that block was registered by Oki Electric Industry — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An OKI OUI in DHCP/ARP is almost always a network printer/MFP — a stable, manageable enterprise asset (note the admin-web default password is often the last six hex of the MAC).
About this vendor.
OKI holds about 4 MA-L blocks registered as "Oki Electric Industry Co., Ltd." (the name also appears uppercased on older blocks — the same company) in Tokyo, Japan, with individual blocks also listing Shibaura and Warabi-shi, Saitama addresses, covering roughly 67.1 million addresses. Verified samples include 00:80:87, 00:11:57, 00:25:36, and 2C:FF:65. These OUIs appear on LED/laser printers, multifunction printers (MFPs), telecom equipment, and ATMs. OKI Data Corporation was OKI's printer subsidiary (Oki Data spun off in 1994), and OKI has since exited Oki-branded printer hardware in key markets — Oki Data Americas ceased sales of all Oki-branded hardware as of 2021-03-31 — while OKI's semiconductor business was sold to Rohm in 2008. Unlike the ODMs in this batch, an OKI OUI maps to the brand. For triage, an OKI OUI in DHCP/ARP is almost always a network printer or MFP — a stable, manageable enterprise asset. (Note the OKI quirk that the device's admin-web default password is often the last six hex digits of its MAC.)

- Special note
- OUI = brand; an OKI MAC in DHCP/ARP is almost always a network printer/MFP. OKI exited Oki-branded printer hardware in some markets (Americas as of 2021-03-31). OKI quirk: the admin-web default password is often the last six hex of the MAC. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
