Action Star Enterprise Co., Ltd. — 00:24:9B (MA-L)

Action Star Enterprise Co., Ltd. holds a single MA-L block, 00:24:9B, registered to a Xizhi District address in New Taipei City, Taiwan. The company is a USB-peripheral and docking-station OEM/ODM founded in 1988, whose products — USB hubs, USB-C/Thunderbolt/USB4 docking stations, and USB adapters — frequently embed USB-to-Ethernet chipsets, which is why a MAC OUI is allocated to it at all. Most of its hardware ships under major brand labels rather than the Action Star name, so this prefix can surface on white-label dock and adapter silicon rather than a consumer-recognizable product. In Q2 2021 the firm was acquired by Simula Technology Inc., a subsidiary of Qisda Corporation (the Taiwanese ODM group formerly known as BenQ), and now operates as Action Star Technology Co., Ltd.; the OUI remains registered under the legacy "Action Star Enterprise Co., Ltd." name. Note a small address discrepancy worth flagging: the IEEE registry lists No. 159, Sec. 2, Datong Rd., while the current company profile lists No. 155 — most likely the registration captured a historical address. As with every OUI, IEEE publishes no assignment date; third-party lookup tools that cite a 2008 "registration date" are reporting a database artifact, not an IEEE fact. No CVEs or security incidents specific to Action Star devices were found in this pass.

IEEE assignment

00:24:9B → Action Star Enterprise Co., Ltd. [Confirmed] — IEEE MA-L (line 20286)

Registry / block size

MA-L (24-bit OUI; range 00:24:9B:00:00:00 – 00:24:9B:FF:FF:FF) [Confirmed] — IEEE MA-L / maclookup.app, uic.io

HQ / country

10F, No. 159, Sec. 2, Datong Rd., Xizhi Dist., New Taipei City 221, TW (registry address; current company profile lists No. 155 — likely a historical address at time of registration) [Confirmed] — IEEE MA-L; actionstar.com.tw/company-profile

Country

TW (Taiwan, ROC) [Confirmed] — IEEE MA-L

Company status

active, as Action Star Technology Co., Ltd. (renamed from Action Star Enterprise Co., Ltd. after Q2 2021 acquisition) [Confirmed] — actionstar.com.tw/company-profile

Founded

1988 [Confirmed] — actionstar.com.tw/company-profile

Device types

USB hubs, USB-C/Thunderbolt/USB4 docking stations, USB adapters, card readers; OEM/ODM devices that commonly embed USB-Ethernet chipsets (hence the MAC allocation) [Confirmed] — actionstar.com.tw, asia-manufacturer.com

Corporate change

acquired Q2 2021 by Simula Technology Inc. (a Qisda Corporation subsidiary; Qisda formerly BenQ); OUI still under the legacy entity name [Confirmed] — actionstar.com.tw/company-profile

Registration date

Unknown — IEEE publishes no OUI assignment date. maclookup.app cites "2008-12-16 registered / 2015-11-17 updated"; these are third-party database artifacts, not IEEE facts. [Unknown for IEEE date; Likely for the artifact values] — maclookup.app

IANA Reference

blank — no IANA reference applies to OUI/MAC assignments [Unknown]

Security context

no CVEs, public vulnerability disclosures, or incidents specific to Action Star devices found this pass; company holds ISO 9001/14001/45001, products carry CE/FCC/RoHS/REACH marks. Absence of CVEs for a niche OEM is not a positive security assurance. [Unknown] — actionstar.com.tw/company-profile

Analyst note

a 00:24:9B OUI identifies an Action Star-manufactured interface, but because the firm is a white-label OEM the device usually carries another brand's name; the prefix indicates the silicon vendor, not the retail brand.
