Guizhou Huaxin Information Technology Co., Ltd. — 2 prefixes (MA-L)

A MAC address beginning with C8:F2:B4 or 60:3C:0E belongs to Guizhou Huaxin Information Technology Co., Ltd., a Chinese automotive-electronics manufacturer, and is typically seen on vehicle-mounted domain-controller hardware such as autonomous-driving central controllers and ADAS domain controllers rather than on consumer or office networking gear.

Both prefixes are standalone MA-L (24-bit OUI) allocations, not slices of a large IEEE-RA shared base — every device carrying either one attributes cleanly to this single registrant. The two registry rows share the same registrant name and the same industrial park in Guian New Area, Guizhou Province, differing only by building number: C8:F2:B4 lists Building 1# and 60:3C:0E lists Building 7#, both at Electronic Information Industry Park of Machang Town, CN 550025.

Beyond the bare IEEE registration, the company shows real operating substance: an active corporate website (hxinfo.com), IATF 16949 / ISO 9001 / ISO 14001 / ISO 45001 certifications scoped explicitly to "Design and Manufacturing of Automotive Data Centers (including: Autonomous Driving Central Controller Assembly, ADAS Domain Controller Assembly, etc.)," and a business-directory profile describing manufacturing and R&D facilities plus branch offices across several Chinese cities. Chinese registry aggregators list an establishment date of 2022-06-15 and registered capital of RMB 200 million.

Two unrelated, similarly-named companies appear in the same registries and must not be conflated with this entry: "Guizhou Huaxintong Semiconductor Technology Co Ltd" (a distinct chip-design firm holding its own OUI, 5C:0C:0E) and "Guizhou Huaxing Information Technology Co., Ltd." (one character different — Huaxing, not Huaxin — with no OUI tie to either prefix here).

No CVE, security advisory, or malware association naming this company or either prefix was found as of an August 2026 web search. IEEE's public OUI data carries no assignment/registration date field for either block; third-party "registration date" values seen on lookup sites are database ingestion artifacts, not IEEE facts.

IEEE assignment

C8:F2:B4, 60:3C:0E → Guizhou Huaxin Information Technology Co., Ltd. (registry string varies slightly by row: with and without a space before "Ltd") [Confirmed] — the IEEE MA-L registry C8F2B4, the IEEE MA-L registry 603C0E

Registry / block size

MA-L (24-bit OUI) × 2 standalone blocks; no MA-M block in the IEEE MA-M registry and no MA-S block in the IEEE MA-S registry for this registrant name [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry

HQ / country

Electronic Information Industry Park of Machang Town, Guian New Area, Guizhou Province, CN 550025 (Building 1# for C8:F2:B4, Building 7# for 60:3C:0E) [Confirmed] — the IEEE MA-L registry C8F2B4, the IEEE MA-L registry 603C0E

Company status

Active (自存续) per Chinese business-registry aggregators; established 2022-06-15, registered capital RMB 200 million, legal representative Zhang Zhifang [Likely — third-party registry aggregator, not a primary filing lookup] — https://qiye.qizhidao.com/company/8d739fd438097702e1ad1ef94c388dda.html

Verified sample prefixes

C8:F2:B4, 60:3C:0E (two standalone MA-L /24 blocks, no MA-M or MA-S entries found) [Confirmed] — the IEEE MA-L registry C8F2B4, the IEEE MA-L registry 603C0E

Historic / additional block

none found beyond the two listed — zero rows in the IEEE MA-M registry and the IEEE MA-S registry for this registrant [Confirmed absence in checked registries] — the IEEE MA-M registry, the IEEE MA-S registry

Registration date

Not published by IEEE for either block; maclookup.app shows third-party ingestion dates (2022-08-27 for C8F2B4, 2024-10-14 for 603C0E) that are database artifacts, not IEEE facts [Confirmed] — the IEEE MA-L registry C8F2B4, the IEEE MA-L registry 603C0E

Security note

No CVE, security advisory, or malware association found as of an August 2026 web search [Unknown — sourced negative]

Special note

Both C8:F2:B4 and 60:3C:0E are standalone MA-L /24 blocks, not slices of a shared IEEE-RA base [Confirmed] — the IEEE MA-L registry C8F2B4, the IEEE MA-L registry 603C0E

Not to be confused with

Guizhou Huaxintong Semiconductor Technology Co Ltd (separate OUI 5C:0C:0E) and Guizhou Huaxing Information Technology Co., Ltd. (similar name, no OUI tie to either prefix here) [Confirmed] — the IEEE MA-L registry 5C0C0E
