Aiwa — 2 MA-L prefixes across two distinct registrants

A MAC address beginning 00:50:71 or A8:01:6D belongs to a company that used the Aiwa brand name, but the two prefixes trace to two separate legal registrants rather than one company holding two blocks. 00:50:71 is registered to AIWA CO., LTD. in Utsunomiya-shi, Tochigi-ken, Japan; A8:01:6D is registered to Aiwa Corporation in Chicago, Illinois, US.

00:50:71 traces to the original Japanese Aiwa Co., Ltd., founded in 1951 as Aiko Denki Sangyo Co., Ltd. and renamed in 1959. It made cassette recorders, portable and mini-component stereos, MiniDisc and CD players, and car stereos through the 1990s. Sony took a controlling stake in 1969, acquired the company outright in December 2002, and discontinued the Aiwa brand in May 2008.

A8:01:6D belongs to Aiwa Corporation, a Chicago brand revival launched in 2015 by Hale Devices, Inc. under Joe Born. It runs a live storefront at aiwa.co selling Bluetooth Exos-series speakers, headphones, and small appliances, corroborated by import records at the same Chicago address. A reported 2020 "unification" with a separately re-established, Japan-based Aiwa Co., Ltd. (Towada Audio, founded 2017) is a brand relationship, not a confirmed shared OUI-registrant identity.

Neither prefix has a device-fingerprint match to a specific product model — the device types below are inferred from each company's known product line, not verified per-MAC. IEEE's public registry publishes no assignment date for either block, and no CVE, security advisory, or botnet report references Aiwa or either prefix as of an August 2026 search.

Prefix 00:50:71

AIWA CO., LTD., Utsunomiya-shi, Tochigi-ken 320-85, JP — original Japanese audio-equipment maker

Prefix A8:01:6D

Aiwa Corporation, 965 W Chicago Ave, Chicago, IL 60642, US — active Bluetooth-audio brand revival

Registry class

Both MA-L (24-bit OUI); no MA-M or MA-S assignment matches "Aiwa" as a whole word

Company relationship

two distinct legal registrants sharing a brand name, not one company with two blocks

Registration date

Unknown — IEEE publishes no assignment/registration date for OUI blocks

IEEE assignment (00

50:71): AIWA CO., LTD., 1-11 Kamitomatsuri 4-chome, Utsunomiya-shi, Tochigi-ken 320-85, JP [Confirmed] — the IEEE MA-L registry 005071

IEEE assignment (A8

01:6D): Aiwa Corporation, 965 W Chicago Ave, Chicago, IL 60642, US [Confirmed] — the IEEE MA-L registry A8016D

Registry scope

exactly two IEEE MA-L assignments match "Aiwa" as a whole word across the IEEE MA-L registry, the IEEE MA-M registry, and the IEEE MA-S registry; a naive substring search also returns "Aiware Inc." (001295), a different, unrelated company whose name merely contains "aiwa" — excluded from this entry

[Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry

Company relationship

two distinct legal registrants that both used the "Aiwa" brand name at different times, not one company with two OUI blocks [Confirmed] — the IEEE MA-L registry 005071, the IEEE MA-L registry A8016D
