Unionman Technology Co., Ltd. — 12 prefixes (MA-L)

Unionman Technology Co., Ltd. (Chinese: 广东九联科技股份有限公司; also rendered 九联科技) is a Huizhou, Guangdong-based hardware manufacturer that holds 12 MA-L (24-bit OUI) blocks, all registered to the same factory address in the Huinan High-Tech Park. Founded in November 2001, the company listed on the Shanghai Stock Exchange STAR Market (科创板, stock code 688609) in March 2021, which makes it an unusually well-documented OUI holder for a Chinese device maker. Its product line is squarely network-edge consumer and carrier hardware: smart network set-top boxes (OTT/IPTV/DVB), GPON/ONU smart home gateways, converged home gateways, smart routers, NB-IoT and LTE cellular IoT modules, 25G fronthaul optical modules, smart cameras, and HarmonyOS/AI edge-computing boards. Its primary customers are Chinese telecom operators, with export sales into South America, the Middle East, Europe, and the United States. One caveat worth recording for security context: Chinese Android set-top boxes as a class have been implicated in botnet campaigns (BadBox, Vo1d), but no public report as of June 2026 names Unionman/九联科技 devices specifically, and the company's operator-channel distribution differs materially from the gray-market off-brand vendors most often affected — so any such association is sector-level inference, not a Unionman-specific finding.

Security context

No CVEs or named vulnerabilities attributed specifically to Unionman products found in NVD/security sources as of June 2026. Sector-level: Chinese Android STBs have been tied to BadBox/Vo1d/Kimwolf botnets, but none of those reports name Unionman; operator-channel distribution differs from the gray-market vendors implicated. No specific threat attribution confirmed.

Analyst note

A Unionman OUI on a globally-administered address identifies genuine Unionman-built carrier/edge hardware (set-top boxes, gateways, modules), commonly seen on operator-supplied CPE. Treat third-party "registration date" values as artifacts, not IEEE facts.
