Shanghai B-star Technology Co. — 2 prefixes (MA-L)
Summary
- // what this is
- Shanghai B-star Technology is registered to MAC prefix
00:F2:2Cand 1 more in the IEEE OUI database. When a device's MAC address begins with00:F2:2C, that block was registered by Shanghai B-star Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Treat as an identifiable Shanghai-based hardware org holding two OUI blocks; do not assume any specific device type or product line without further sourcing. Do not surface maclookup.app dates as IEEE registration dates.
About this vendor.
Shanghai B-star Technology Co. holds two separate MA-L (24-bit) OUI blocks in the current IEEE registry mirror — 00:F2:2C, registered as "Shanghai B-star Technology Co.,Ltd.", and 7C:08:D9, registered as "Shanghai B-Star Technology Co." — both filed under the same Changning District address on Xiehe Road, Shanghai, postal code 200335, with only cosmetic differences in punctuation and suite detail between the two registry rows. Holding two independent OUI assignments at one address is a modest but real signal of an active hardware manufacturer rather than a bare shell registration, since IEEE issues each MA-L block against a separate fee and application. That said, research beyond the registry itself turned up little: no company website, no product or device documentation, no hit in Chinese business registries (qcc.com, tianyancha) for the company name, and no security or abuse reports tied to either prefix. A Bloomberg Markets profile stub confirms the legal-entity name exists but the page itself returned an HTTP 403 on fetch, so no further description could be verified. Third-party lookup tools (maclookup.app) display "registered" dates for both prefixes, but IEEE's own OUI data publishes no assignment date — those values are database artifacts and are not recorded here as facts.
- IEEE assignments
- 00:F2:2C → "Shanghai B-star Technology Co.,Ltd."; 7C:08:D9 → "Shanghai B-Star Technology Co" [Confirmed] — IEEE MA-L (cross-checked at https://standards-oui.ieee.org/oui/oui.csv)
- Registry / block size
- MA-L (24-bit OUI) x2 blocks, same organization at same address [Confirmed] — IEEE MA-L
- Registered address
- 4th Floor, No.1158 Xiehe Road, Changning District, Shanghai, China 200335 (identical across both blocks, minor formatting variance only) [Confirmed] — IEEE MA-L
- Country
- CN [Confirmed] — IEEE MA-L
- Company status
- Unknown — no company website found; no match in Chinese business registries (qcc.com, tianyancha) searched under the Chinese-language company name [Unknown] — negative search, see W1-web notes
- Device types / usage context
- Unknown — no product, device, or router/IoT association surfaced in English or Chinese search [Unknown] — W1-web
- Company substance signal
- two independent MA-L OUI assignments at one address, which under this pipeline's abstain-on-shells rule is treated as verifiable substance beyond a bare single-OUI registration [Likely] — inference from registry data, not an external corroborating source
- Legal-entity confirmation
- a Bloomberg Markets company profile page exists for the entity name, but the page returned HTTP 403 on fetch so its content could not be verified beyond the URL existing [Likely] — https://www.bloomberg.com/profile/company/1386385D:CH
- Registration date caveat
- maclookup.app shows "registered 2016-06-27" for 00:F2:2C and "registered 2010-01-05 / updated 2015-11-17" for 7C:08:D9; these are third-party database artifacts, NOT IEEE facts (IEEE's the IEEE MA-L registry carries no date column) — not recorded as an entry date [Confirmed] — https://maclookup.app/vendors/shanghai-b-star-technology-co-ltd, https://maclookup.app/vendors/shanghai-b-star-technology-co
- MAM/OUI-36 coverage
- no matching rows in the IEEE MA-M registry or the IEEE MA-S registry for this organization [Confirmed] — registry Grep
- Security context
- no CVEs, advisories, or abuse reports found tied to either prefix [Unknown] — W1-web negative search
