shenzhen Cloud High Communication Technology Co.,Ltd — 40:E1:1C (MA-L)

OUI 40:E1:1C is a single MA-L (MAC Address Block Large) registered to "shenzhen Cloud High Communication Technology Co.,Ltd," a manufacturer based in Bao'an District, Shenzhen, China. The block resolves consistently across IEEE-derived lookup databases, and the registry address (Room 1908, Building 1, Jinlitong Financial Center Building, No. 1100 Xingye Road, Haiwang Community, Xin'an Street, Bao'an District, Shenzhen 518128) matches between the local the IEEE MA-L registry copy and third-party tools. Beyond the registration itself, public corroboration is thin: no official vendor website, no FCC ID filings, and no product listings surface for this organization. The company name and the MA-L allocation point toward networking or communication equipment, but no specific device category (router, IoT module, wireless gear) can be confirmed from available sources, so the device type stays Unknown rather than guessed. A common data-quality trap to flag: the 28-bit MA-M prefix F4:0E:11:C belongs to a different organization (NIHON MEGA LOGIC CO.,LTD.) and is not a match for the 24-bit OUI 40:E1:1C. No threat intelligence, CVEs, or security advisories are associated with this OUI; as with any unrecognized OEM lacking public certification, standard network hygiene (segmentation, firmware provenance checks) is prudent, but no specific risk is known.

IEEE assignment

40:E1:1C → shenzhen Cloud High Communication Technology Co.,Ltd [Confirmed] — IEEE the IEEE MA-L registry (MA-L), maclookup.app/macaddress/40E11C

Registry / block size

MA-L (24-bit OUI; ~16.7M addresses) [Confirmed] — IEEE the IEEE MA-L registry, maclookup.app

HQ / country

Room 1908, Building 1, Jinlitong Financial Center Building, No. 1100 Xingye Road, Haiwang Community, Xin'an Street, Bao'an District, Shenzhen, China 518128 — CN [Confirmed] — IEEE the IEEE MA-L registry, maclookup.app/macaddress/40E11C

Registration date

IEEE publishes NO assignment/registration date for OUI/MAC prefixes (the IEEE MA-L registry columns are only Registry, Assignment, Organization Name, Organization Address). maclookup.app surfaces "July 13, 2022," but that is a third-party database artifact, not an IEEE fact, and is recorded only as such. [Likely third-party artifact; not authoritative] — maclookup.app/macaddress/40E11C

Company status

Unknown — no official vendor website or company registry record confirmed [Unknown]

Device types

Unknown — no public product listings, FCC filings, or manufacturer site found; name + MA-L block suggest networking/communication equipment but no category confirmed [Unknown]

Vendor website

Unknown — no official site located [Unknown]

FCC filings

None found — no FCC ID returned from fccid.io or FCC search for this vendor [Likely none]

Data trap

the MA-M hit F4:0E:11:C is a DIFFERENT 28-bit prefix (NIHON MEGA LOGIC CO.,LTD.) and is NOT a match for the 24-bit OUI 40:E1:1C. [Confirmed] — IEEE the IEEE MA-L registry

Security context

No CVEs, threat intel, or advisories tied to 40:E1:1C or this vendor. Relatively new/small Chinese OEM (single MA-L block). Unrecognized OEMs without public FCC certification or product docs warrant standard network hygiene (segmentation, firmware provenance), but no specific known risk.

[Likely] — no public security source found

Analyst note

A 40:E1:1C globally-administered address identifies hardware from this vendor, but with no confirmed product line or website the device behind it cannot be characterized further from OUI alone.
