Shenzhen Fenda Technology Co., Ltd — 3 prefixes (MA-L)

A MAC address beginning with AC:B1:EE, F0:13:C3, or CC:BF:0C belongs to Shenzhen Fenda Technology Co., Ltd, a Shenzhen-based consumer electronics manufacturer — most plausibly a WiFi-connected speaker or smart door lock from its product line rather than one of its Bluetooth-only or wearable devices.

Shenzhen Fenda Technology Co., Ltd is publicly traded on the Shenzhen Stock Exchange SME board (ticker 002681), with an IPO in 2012. Company-history summaries state it was founded in 1993 as Shenzhen Baoan Fenda Industry Co., Ltd and renamed to its current name in 2010. Its Baoan District, Shenzhen headquarters matches the IEEE registry address for all three prefixes.

The company manufactures electroacoustic products — wireless Bluetooth speakers, WiFi speakers, AI/smart voice speakers, Airplay-compatible soundbars, power-bank speakers, and home-theater systems — plus smart wearables (watches, bracelets, rings, helmets, health monitors) and smart door locks, both under its own brand and as OEM/ODM manufacturing for other brands.

Bluetooth-only speakers and most wearables typically surface a MAC sourced from a third-party Bluetooth chipset vendor rather than the OEM's own IEEE-registered OUI. That makes the WiFi/AI/Airplay speaker sub-lines, or a WiFi-enabled smart lock, the stronger match for a device actually presenting one of these three prefixes; this mapping is inferred from the product catalog rather than confirmed against a device teardown.

Two adjacent, textually similar OUI registry entries should not be folded into this vendor. "Shenzhen trolink Technology Co.,Ltd" holds separate prefixes registered at the same Fenda Hi-Tech Park address — a different, already-documented vendor that happens to share an industrial-park address, not a corporate relation. "Shenzhen Baoan Fenda Industrial Co., Ltd" holds prefix 00:27:21 at the same address under a distinct registrant string; it is a plausible but registry-unconfirmed match for this company's pre-2010 name, and that prefix is excluded from this entry.

No Fenda-specific CVE, botnet, or IOC entry was found as of an August 2026 search across NVD and general web search. As with any unmanaged WiFi speaker, smart lock, or wearable from a Chinese ODM, firmware trust is a property of the specific end product and its companion app, not something demonstrated by the OUI holder alone.

Registered prefixes

AC:B1:EE, F0:13:C3, CC:BF:0C (IEEE MA-L)

Device class

WiFi-connected speakers (AI/WiFi/Airplay lines) or a smart door lock are the most plausible source of a MAC in this range

Weaker match

Also manufactures

soundbars, power-bank speakers, home-theater systems, smart watches/bracelets/rings, health monitors

Not to be confused with

"shenzhen trolink Technology Co.,Ltd" (separate vendor, same industrial-park address) and "Shenzhen Baoan Fenda Industrial Co., Ltd" (prefix 00:27:21, unconfirmed same-entity)
