Panasonic Appliances Company — 5 prefixes (4× MA-L + 1× MA-M)
Summary
- // what this is
- Panasonic Appliances is registered to MAC prefix
D8:AF:F1and 4 more in the IEEE OUI database. When a device's MAC address begins withD8:AF:F1, that block was registered by Panasonic Appliances — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Company substance beyond a bare registration: multiple OUI blocks (4 MA-L + 1 MA-M) across two registrant entities, both tied to identifiable, still-active Panasonic business units and a real registered facility (Kusatsu, Shiga). Device mapping is general (smart-appliance app ecosystem), not prefix-specific -- do not infer a specific device model from OUI alone.
About this vendor.
A MAC address beginning with D8:AF:F1, 80:C7:55, 34:31:7F, or B4:6C:47 belongs to Panasonic Appliances Company, the Panasonic business unit registered in Kusatsu, Shiga, Japan that today sits under Panasonic's Living Appliances and Solutions Company umbrella, making connected home appliances such as air conditioners, washing machines, refrigerators, and dehumidifiers.
A fifth, smaller prefix — 2C:69:1D:A0/28 — is a separate MA-M sub-allocation registered to Panasonic Appliances Marketing Asia Pacific in Petaling Jaya, Selangor, Malaysia. It is a distinct registrant entity from the Japan-based parent and should not be folded into the same prefix count.
No source ties any of these five prefixes to a specific named product model. General corroboration comes only from Panasonic's Smart Wifi/Smart appliance apps and a community Home Assistant integration, both describing Wi-Fi-connected climate, laundry, and refrigeration appliances consistent with an "Appliances Company" registrant, but neither is prefix-specific.
Third-party lookup sites show per-prefix "registered" dates ranging from 2012-05-26 through 2021-06-17; these are database artifacts, not IEEE facts — the public IEEE registry publishes no assignment-date field for MAC prefixes, and none should be attributed to IEEE.
