Mercury Communication Technologies Co.,Ltd. — 8 prefixes (MA-L)

The IEEE MA-L registry lists eight OUI blocks under the exact organization string "MERCURY COMMUNICATION TECHNOLOGIES CO.,LTD." (no "Shenzhen" prefix), all sharing one registered address in Nanshan District, Shenzhen — a spread consistent with an active hardware manufacturer rather than a one-off single-block registrant, which is the bar this pipeline uses to keep a vendor page live instead of gating it as a thin shell. This registrant is legally and physically distinct from "SHENZHEN MERCURY COMMUNICATION TECHNOLOGIES CO.,LTD.," a separately registered, already-published vendor with nineteen of its own MA-L blocks and a different building address; the two names are easy to conflate but the registry keeps them apart. A same-cycle web-research pass aimed at this entry instead surfaced product and corporate detail for that Shenzhen-prefixed sibling, so no independent company website, product line, or industry confirmation exists yet for this specific registrant — those facts are recorded honestly as unknown below rather than borrowed across the entities.

IEEE assignment

8 MA-L prefixes → MERCURY COMMUNICATION TECHNOLOGIES CO.,LTD. [Confirmed] — the IEEE MA-L registry lines 1934, 9974, 9975, 17818, 25762-25765

Registry / block size

MA-L (24-bit OUI) for all 8 blocks [Confirmed] — the IEEE MA-L registry

HQ / registered address

Mid-Fourth Flr., Building 28, Cui Xi Fourth Road, Ke Yuan West, Nanshan, Shenzhen, Guangdong, CN 518057 (one of the 8 rows carries a full-width comma glyph after "Road" instead of ASCII — a registry-side typo, not a different address)

[Confirmed] — the IEEE MA-L registry lines 1934, 9974, 9975, 17818, 25762-25765

Verified prefixes (all MA-L, same organization string)

48:8A:D2, BC:5F:F6, C8:E7:D8, 8C:F2:28, F4:EE:14, 6C:59:40, D0:25:16, 1C:60:DE [Confirmed] — the IEEE MA-L registry

MA-M / MA-S cross-check

no MA-M block for this org in the IEEE MA-M registry; the one "MERCURY" MA-S hit in the IEEE MA-S registry (00:1B:C5:00A, "Mercury HMI Ltd," Malton, North Yorkshire, GB) is an unrelated UK company, not this registrant [Confirmed] — the IEEE MA-M registry, the IEEE MA-S registry line 1087

Distinct from Shenzhen-prefixed variant

"SHENZHEN MERCURY COMMUNICATION TECHNOLOGIES CO.,LTD." is a separate, already-DONE master entry (19 MA-L blocks, different building address); the checker's prior PASS explicitly verified the two must stay split

[Confirmed] — this site's own enrichment records line 2612, this site's own enrichment records line 1180

Company status / website / product line

not independently confirmed for this exact registrant — the same-cycle web-research angle's findings (mercurycom.com.cn, "Mercury"/水星 consumer router brand, TP-Link family linkage) describe the distinct Shenzhen-prefixed sibling, not this one, and are not attributed here to avoid conflating two registry entities

[Unknown] — no citation carried over from mismatched research

Device / industry context

Unknown for this specific registrant; the shared "Mercury Communication Technologies" naming and Nanshan/Shenzhen locale resemble the sibling's consumer-networking profile, but that is an unconfirmed inference, not a verified fact [Unknown]

Registration dates

not applicable — IEEE's public OUI data publishes no assignment/registration date for any block; none invented [Confirmed] — the IEEE MA-L registry (column set: Registry, Assignment, Organization Name, Organization Address)
