Shenzhen Coship Electronics Co., Ltd. — 5 prefixes (MA-L)

A MAC address starting with one of five prefixes — 58:87:E2, 84:62:23, 94:BA:56, 94:BF:95, or A4:A8:0F — belongs to Shenzhen Coship Electronics Co., Ltd., a Chinese manufacturer whose hardware is most often a set-top box (STB) or related digital-TV device.

Coship is not a bare shell registrant. Founded in 1994 and listed on a Chinese stock exchange in 2006 (stock code 002052), the company describes itself as China's largest STB maker, with tens of millions of units deployed alongside digital-TV middleware and interactive-platform products.

Independent trade press corroborates the device context: Coship has shipped IP set-top boxes built on Conexant chipsets and HD set-top boxes using Trident Microsystems chipsets for the China market, and an independent teardown examined a Coship CDVB2300A set-top box.

The same corporate family also registers OUIs under two related-but-distinct names — Shenzhen Coship Software Co.,LTD. (00:0E:09) and Nantong Coship Electronics Co., Ltd. (68:DB:67, 6C:8A:EC) — which are separate vendor entries, not part of this bucket. Two CVEs (an XSS flaw and an unauthenticated Wi-Fi password reset) are documented against Coship's wireless-router firmware line, a related but distinct product line from the STB hardware the OUI address points to.

58:87:E2, 84:62:23, 94:BA:56, 94:BF:95, A4:A8:0F [Confirmed] — the IEEE MA-L registry

Historic block

none identified pre-dating these five; no first-party IEEE assignment date exists to establish one [Unknown] — IEEE does not publish OUI dates

Special note

maclookup.app shows "First Seen 2010-07-26" / "First Seen 2014-07-13" timestamps for two name-variant entries — these are third-party database crawl artifacts, NOT IEEE registration dates, and are not recorded as fact [Confirmed] — maclookup.app

Related vendors

Shenzhen Coship Software Co.,LTD. (00:0E:09) and Nantong Coship Electronics Co., Ltd. (68:DB:67, 6C:8A:EC) — same corporate family, distinct registry entries/slugs [Confirmed] — the IEEE MA-L registry

Analyst note

A Coship OUI on a globally-administered address reliably identifies set-top-box or related digital-TV hardware from an established, decades-old manufacturer — not a bare shell registration; two related legal entities in the same corporate family hold separate OUIs and should not be merged into this entry.
