Nantong Coship Electronics Co., Ltd. — 2 prefixes (MA-L)

A MAC address beginning 6C:8A:EC or 68:DB:67 belongs to Nantong Coship Electronics Co., Ltd., typically seen on digital-TV set-top boxes and related consumer-electronics hardware built at its Nantong, Jiangsu manufacturing site, per the IEEE MA-L registry and the parent company's own subsidiary profile.

Nantong Coship Electronics is a wholly-owned manufacturing subsidiary of Shenzhen Coship Electronics Co., Ltd. (Shenzhen Stock Exchange code 002052), established in 2007 with registered capital of 290 million RMB and 1,000+ employees. The parent's own site states the Nantong facility's capacity at 10 million HD set-top-box units per year, plus PCBA/EMS contract manufacturing (SMT, DIP, assembly, testing) for other customers.

That corporate context, combined with two independent MA-L assignments under the exact registered name rather than one bare registration, is what lifts this entry above a single-OUI shell. Independent, non-parent-site corroboration of the device type exists only at the broader "Coship" brand level — an Electronics360 teardown of a Coship set-top box and an FCC ID filing for a "COSHIP ELECTRONICS" set-top box — neither names the Nantong subsidiary or ties a unit to these specific prefixes.

The IEEE registry's 68:DB:67 row lists country "US" while carrying the same street address (No.188 Xinsheng Road) and city (Nantong) as the 6C:8A:EC row; the postal code differs (226001 vs 226000) and the province token "Jiangsu" is absent from the 68:DB:67 row entirely. This reads as a mis-keyed field in the IEEE snapshot rather than a real second location. IEEE's public OUI data carries no assignment date field, so any "date registered" shown by third-party lookup tools for either prefix is a database crawl timestamp, not an IEEE fact.

No CVE or advisory attributed to Nantong Coship specifically was found as of an August 2026 search. The only documented Coship-family vulnerabilities (an unauthenticated admin-password-reset flaw and a separate XSS report) are attributed in every source to Shenzhen Coship router firmware — a different entity and product line — and should not be read as this entity's security history.

Nantong Coship Electronics stays a distinct vendor bucket, cross-linked to but not merged with Shenzhen Coship Electronics Co., Ltd. (the parent, holding 5 of its own MA-L prefixes) and Shenzhen Coship Software Co., Ltd. (a separate, unrelated OUI registrant).

Registry data-quality note

the 68:DB:67 row lists country "US" while sharing the same street address (No.188 Xinsheng Road) and city (Nantong) with the 6C:8A:EC row; the postal code differs (226001 vs 226000) and the province token "Jiangsu" is absent from the 68:DB:67 row — read as a mis-keyed field in the IEEE snapshot, not a real second location

Device-type corroboration caveat

independent evidence (teardown, FCC filing) exists only at the broader "Coship" brand level and does not name the Nantong subsidiary or these specific prefixes [Likely] — https://electronics360.globalspec.com/article/3388/coship-cdvb2300a-set-top-box-teardown, https://fccid.io/VXF2008011602/User-Manual/Users-Manual-1015151

Analyst note

two OUI assignments plus a documented parent-subsidiary manufacturing role place this above a bare single-OUI shell registration, but device-type corroboration is inferred through the parent site rather than independently confirmed per-device; Shenzhen Coship router-firmware CVEs belong to a different entity and should not be attributed here.
