Wuhan Tianyu Information Industry Co., Ltd. — 6 prefixes (MA-L/MA-M)

A MAC address starting with 2C:7C:E4, 4C:80:BA, AC:20:3E, or B8:32:41, or falling inside the MA-M ranges 74:F8:DB:7/28 or 08:26:AE:0/28, belongs to Wuhan Tianyu Information Industry Co., Ltd., a publicly traded Chinese electronics manufacturer whose documented hardware line is smart-card and smart-POS / mPOS payment terminals. The 74:F8:DB and 08:26:AE bases themselves are IEEE-administered and shared with unrelated registrants, so only those two /28 slices are Wuhan Tianyu's.

The company is real and substantive, not a shell registrant. It is listed on the Shenzhen Stock Exchange ChiNext board under ticker 300205, was founded in August 1999, and has roughly 1,055 employees headquartered in Wuhan, Hubei. It has been publicly traded since April 2011.

Six independent IEEE prefixes are registered under this exact company name and address: four MA-L (24-bit) blocks — 2C7CE4, 4C80BA, AC203E, B83241 — plus two MA-M (28-bit) blocks, 74F8DB7/28 and 0826AE0/28. Holding six separate allocations across two registry classes is itself a substance signal beyond a bare single-OUI registration.

No specific MAC prefix was matched to a specific device model, so per-prefix attribution (which product line uses which block) stays Unknown. The company's documented product line — P10, P20, P20L, P30, P40, S30, S40, and TP50 smart-POS / mPOS terminal models — is consistent with networked (Wi-Fi/Bluetooth/Ethernet) payment hardware needing MAC address space, but that link is inferential, not prefix-verified.

No CVEs or security advisories specific to Wuhan Tianyu hardware were found. One search lead, CVE-2024-48440, was checked directly against NVD and ruled out — it describes a "Tianyu CPE Router" but belongs to a different company, Shenzhen Tuoshi Network Communications Co., Ltd. Absence of findings is reported as Unknown, not asserted as "clean."

Analyst note

six independent OUI assignments (4 MA-L + 2 MA-M) under one registrant identity, combined with a verifiable publicly traded corporate profile and a documented POS/mPOS product line, establish company substance beyond a bare single-OUI shell — this vendor is identifiable and real, not a token registration.
