Tonly Technology Co. Ltd — 10 prefixes (MA-L)

A MAC address beginning with 88:D0:39 — one of ten IEEE MA-L blocks registered to the same organization — identifies Tonly Technology Co. Ltd, an ODM electronics manufacturer based in Huizhou, Guangdong, China. Devices carrying these prefixes are typically consumer electronics built for other brands: TV set-top boxes, Bluetooth/Wi-Fi audio speakers and headphones, wearables, and other AIoT products.

Tonly Technology Co. Ltd sits under Tonly Electronics Holdings Limited, a company listed on the Hong Kong Stock Exchange (1249.HK) and formerly known as TCL Tonly Electronics (Huizhou) Co., Ltd. The corporate history page states the firm was founded in 2000 and describes an R&D team of more than 2,200 engineers, consistent with a large-volume contract manufacturer rather than a single-product vendor.

IEEE's registry confirms ten separate MA-L (24-bit) OUI assignments to this exact organization name and Huizhou address, with no MA-M or MA-S sub-blocks found in the cached registry files. Multiple independent block registrations under one consistent identity is itself evidence of an active, ongoing manufacturer rather than a one-off or shell registrant.

A separate, unrelated firm also trades under the name "Tonly" — Shenzhen Tonly Technology Co. Ltd, which makes AV-over-IP, KVM, and wireless-presentation hardware. Its own site shows no connection to the Huizhou-based, HKEX-listed entity that actually holds these OUI blocks; the two histories should not be conflated when identifying a device from its MAC prefix.

No CVEs or named security advisories referencing Tonly-branded or Tonly-manufactured devices turned up in a targeted search, so device-level security posture is unknown. Because Tonly manufactures as an ODM, end products often ship under other brand names, which can make the MAC prefix alone insufficient for identifying the retail-facing device name.
