Tenda Technology Co.,Ltd.Dongguan branch — 11 prefixes (MA-L)

Tenda Technology Co.,Ltd. Dongguan branch is a China-based registrant branch of Tenda, a Shenzhen-founded (1999) consumer and SOHO networking-hardware OEM whose product line spans Wi-Fi routers, managed and unmanaged switches, broadband CPE/gateways, powerline adapters, and IP cameras/NVRs sold across 120+ countries. This exact registrant name holds eleven distinct IEEE MA-L (OUI-24) blocks — 04:95:E6, 08:40:F3, 50:0F:F5, 50:2B:73, 58:D9:D5, B0:DF:C1, B4:0F:3B, B8:3A:08, CC:2D:21, D8:32:14, and E8:65:D4 — all sharing one identical registered address (Room 79, Yuanyi Road, Dalang Town, Dongguan, Guangdong 523770, CN), consistent with a single manufacturing branch drawing repeated blocks as device volume grew. The company is distinct from two similarly-named registry entries — Shenzhen Tenda Technology Co.,Ltd. and a separately-addressed "Tenda Technology Co., Ltd." (Shenzhen HQ) — which hold their own separate OUI blocks and must not be merged into this entry. Tenda-brand router firmware currently carries an actively disclosed, unpatched CVE (CVE-2026-11405): a CERT/CC-reported hardcoded-credential backdoor in several consumer router families, rated CVSS 9.8 for unauthenticated full admin takeover — vendor-level risk context relevant to any device identified by these prefixes, though not confirmed specific to this branch's blocks alone.

Assignment/registration date

Unknown / not applicable — IEEE's public the IEEE MA-L registry publishes no assignment-date field.
