Arounds Intelligent Equipment Co., Ltd. — 3C:B0:7E (MA-L)

OUI 3C:B0:7E is a single MA-L (MAC Address Block Large) assignment registered to Arounds Intelligent Equipment Co., Ltd., a company based in Chengdu, Sichuan, China. The block covers 3C:B0:7E:00:00:00 through 3C:B0:7E:FF:FF:FF — roughly 16.7 million globally-administered unicast addresses for the registrant's own hardware. The vendor identity is consistent across four independent MAC lookup sources (maclookup.app, oui.is, the macvendors.com API, and aruljohn.com), all returning the same company name and the same Chengdu registry address (Room 701-703, Vanke Huamao Plaza, No. 508, East 2nd Section, 2nd Ring Road, Chenghua District). Beyond the registry record itself, public information on this company is sparse: web search surfaced no official website, no product listings, no FCC filings, and no device-type disclosures in either English or Chinese sources. That low public footprint is consistent with a small OEM, white-label, or industrial-equipment maker, but the device class cannot be confirmed from available data and is recorded as Unknown rather than guessed. No CVEs, vulnerability advisories, or threat-intelligence reports referencing this OUI or this organization were found, so no security flag is asserted here. Per project policy, no registration date is recorded: IEEE publishes no OUI assignment dates, and the "date registered" fields shown by third-party lookup tools are database artifacts rather than IEEE facts.

Analyst note

Vendor identity is well-corroborated (4 independent sources agree), but everything downstream of the registry record — device class, company status, official site — is unverifiable from public data. Treat 3C:B0:7E as a confirmed Arounds-owned prefix of unknown device type.
