MAC address vendor

Luxottica Tristar (Dongguan) Optical Co., Ltd — 2 prefixes (MA-L)

Primary prefix
38:47:12
Block
MA-L
Status
Active

Summary

// what this is
Luxottica Tristar is registered to MAC prefix 38:47:12 and 1 more in the IEEE OUI database. When a device's MAC address begins with 38:47:12, that block was registered by Luxottica Tristar — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Two convergent MA-L assignments to an identifiable, well-documented EssilorLuxottica manufacturing subsidiary clear the abstain-on-shells bar; device-type/product tie (Ray-Ban Meta) is plausible but sourced only to secondary reporting, so keep that claim tagged Likely rather than Confirmed.

About this vendor.

Updated  ·  Confidence: Medium

Luxottica Tristar (Dongguan) Optical Co., Ltd. is a wholly foreign-owned manufacturing subsidiary of the Italian Luxottica Group (now EssilorLuxottica, owner of Ray-Ban and Oakley), established in 1997 in Gaobu Town, Dongguan City, Guangdong, China. Two distinct IEEE MA-L OUI blocks — 38:47:12 and 80:AA:1C — resolve to an identical registrant name and address for this entity, a signal of real production volume rather than a one-off registration. Secondary Chinese-language corporate reporting (Baidu Baike) describes the site as EssilorLuxottica's largest eyewear production base worldwide: roughly US$140.7M registered capital, a 150,000+ sq m second production base completed in 2006, over 5,200 staff, and Customs AEO Advanced Certification obtained in 2023. That same source credits the facility with growing exports of "AI smart glasses" in 2023, which plausibly — though not confirmed by a primary EssilorLuxottica or Meta source — ties its network hardware to EssilorLuxottica's Ray-Ban Meta smart-glasses line, a Wi-Fi and Bluetooth-enabled camera/audio wearable co-developed with Meta. No CVEs or vendor security advisories were found under this registrant name. This entry is distinct from the unrelated MA-L registration for "LUXOTTICA GROUP S.P.A." at the Milan corporate address, which belongs to the parent holding company, not this Dongguan manufacturing subsidiary.
