Shenzhen OXO Technology Limited — 20:80:97 (MA-L)

OUI 20:80:97 is a single MA-L block registered to Shenzhen OXO Technology Limited, a Longgang District, Shenzhen manufacturer founded around 2020. The company is the maker behind the IIIF150 rugged-smartphone brand, an Android handset line aimed at outdoor users that includes the B-series (B2 Pro, B2 Ultra, B3), the Air1 Ultra, and the Raptor 5G. Because the products are consumer Android phones rather than networking appliances or IoT infrastructure, MAC addresses from this prefix turning up on enterprise sensors typically signal personal, bring-your-own devices rather than purpose-built network gear. The name OXO causes real disambiguation trouble: a separate Shenzhen OXO Network Limited in Dongguan makes communication cables and is not the registrant, and oxotechnology.com is an unrelated Spanish dental-camera company — neither should be conflated with this OUI holder. As with MAC prefixes generally, IEEE publishes no assignment date for this block, so any "date registered" seen on third-party lookup sites is a database artifact rather than a first-party fact, and the allocated date stays Unknown here.

Analyst note

consumer handset OUI, not network gear; addresses on enterprise sensors indicate BYOD personal devices, not infrastructure.
