Dongguan Cannice Precision Manufacturing Co., Ltd. — 2 prefixes (MA-L)

The IEEE MA-L registry carries two separate 24-bit OUI blocks — 6C:0D:E1 and F0:BE:25 — under the identical legal name "Dongguan Cannice Precision Manufacturing Co., Ltd.," which by itself clears the multi-OUI substance bar even before any outside context. The two blocks list different registered street addresses in the same city (Dongguan, Guangdong, CN), which reads as two manufacturing sites or filing rounds for one company rather than two coincidentally-named firms. "Cannice" is not an isolated name in the registry: it also appears as the trade name behind a separate MA-L holder, "Guangxi Konaixin Precision Technology Co., Ltd." (90:A0:BE), whose registered address matches a Cannice-branded manufacturing-center description on cannice.com, and as the direct legal name of "Shenzhen Cannice Technology Co., Ltd." (B8:EF:8B), an identifiable, currently active consumer-electronics brand making Bluetooth TWS earbuds, open-ear earbuds, Bluetooth hearing aids, smart glasses, and headsets, with FCC filings under grantee code 2ADTV. No independent website, business registry listing, or FCC filing was found under the Dongguan entity's own exact name, so its link to the wider Cannice group — real as the pattern looks — is inferred, not documented first-party.

IEEE assignment

two MA-L prefixes, 6C:0D:E1 and F0:BE:25, both registered to "Dongguan Cannice Precision Manufacturing Co., Ltd." [Confirmed] — the IEEE MA-L registry (lines 9062, 32362; local IEEE MA-L snapshot)

Registry / block size

MA-L (24-bit OUI) x2 for this exact entity name; no match for "Cannice" in MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) [Confirmed] — the IEEE MA-M registry, the IEEE MA-S registry (both zero hits)

Registered addresses

6C:0D:E1 lists only the company name as its address line; F0:BE:25 lists "No. 21, Nange West Road, Daojiao Town, Dongguan, Guangdong, CN 523170" — same city/province/country, different street address between the two blocks [Confirmed] — the IEEE MA-L registry

Registration date

Unknown / not applicable — IEEE's MA-L CSV publishes only Registry, Assignment, Organization Name, and Organization Address, no date column, for either block. Third-party maclookup.app shows "first seen" 2020-11-17 (6C:0D:E1) and 2021-11-11 (F0:BE:25); these are crawl/database artifacts, not IEEE registration dates, and are not recorded as such

Company status / independent footprint

no website, corporate-registry (e.g. qcc.com), or FCC filing was found under the exact name "Dongguan Cannice Precision Manufacturing Co., Ltd." A search-snippet claim tying the Daojiao Town address to a 66,666 sqm "Cannice Manufacturing Center" could not be confirmed on cannice.com's live manufacturing page, which showed only a separate Guangxi facility

Related registrants sharing the "Cannice" name

Guangxi Konaixin Precision Technology Co., Ltd., trading as "Cannice" (90:A0:BE) — its registered address matches the Guangxi manufacturing-center details published on cannice.com; and Shenzhen Cannice Technology Co., Ltd. (B8:EF:8B), the identifiable brand owner behind cannice.com, an active TWS-earbuds/hearing-aid/smart-glasses maker with FCC filings under grantee code 2ADTV [Likely — group affiliation inferred from name/address pattern, not from a corporate-structure document] — the IEEE MA-L registry (lines 6688, 17531); https://www.cannice.com/pdy/index.aspx; https://fccid.io/2ADTV-0W2

Device types

none confirmed for the Dongguan entity itself; if it is part of the wider Cannice group, the group's product line is Bluetooth/TWS consumer audio (earbuds, open-ear earbuds, hearing aids, smart glasses, headsets) rather than networking infrastructure hardware [Likely for the group line; Unknown as applied to this specific entity] — https://www.cannice.com/

Security context

no vendor-specific CVE found for "Cannice" or "Dongguan Cannice Precision Manufacturing" in any form; Bluetooth TWS/audio devices generally sit in the standard Bluetooth-pairing threat class (and, for Airoha-chipset devices specifically, the 2025 CVE-2025-20700/20701/20702 RACE-protocol issues), but no evidence links any Cannice-branded product to an Airoha chipset [Confirmed for the null CVE result; Unknown/speculative beyond that] — web search (no Cannice-specific CVE results); https://cyberpress.org/new-bluetooth-headphone-vulnerabilities/ (class-level context only)

Company substance assessment

qualifies for finalization on the multiple-OUI-assignments criterion alone (2 MA-L blocks under this exact legal name), reinforced by a Likely — not Confirmed — link to a broader, identifiable "Cannice" manufacturing/brand cluster (4 MA-L blocks across 3 registrant names)
