Beijing Sankuai Online Technology Co., Ltd — 2 prefixes (MA-L)

Beijing Sankuai Online Technology Co., Ltd is the legal operating entity behind Meituan (美团), the Chinese on-demand delivery and local-services platform; "Sankuai" (三快) is the company name, while Meituan is the consumer-facing brand. The entity holds two MA-L (24-bit OUI) blocks in the IEEE registry — 84:4B:B7 and E8:81:AB — together granting roughly 33.6 million MAC addresses (2 × 2²⁴). The two blocks carry different Beijing addresses on record: 84:4B:B7 lists Wangjing International R&D Park, and E8:81:AB lists the China Electronic Science Taiji Information Technology base on Rongda Road, both in Chaoyang District, postcode 100102. Neither block appears in the MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) registries — the assignments are MA-L only. No device-type field exists in IEEE's public OUI data, and no public packet captures, CVEs, or security disclosures tie a specific Sankuai-addressed device to these prefixes, so concrete hardware identification is Unknown. A fleet-scale dual-MA-L allocation is, however, consistent with Meituan's known connected-hardware lines: autonomous ground-delivery vehicles, NB-IoT bike-share locks (Meituan Bike / Mobike), drone-delivery units, and POS/restaurant terminals. The corporate identity is independently corroborated by USPTO trademark filings for MEITUAN held by the same Beijing Sankuai entity. A practical caveat for analysts: as with any vendor OUI, a globally-administered 84:4B:B7 or E8:81:AB address identifies genuine Sankuai-registered hardware, but the absence of one does not prove a device is not Sankuai-built, and no IEEE registration date exists for either prefix.

IEEE assignment

2 prefixes → "Beijing Sankuai Online Technology Co.,Ltd", Beijing, Chaoyang District, CN [Confirmed] — IEEE MA-L (lines 667, 19204; corroborated in the Wireshark manufacturer database lines 38912, 54431)

Registry / block size

MA-L (24-bit OUI); 2 IEEE prefixes 84:4B:B7 and E8:81:AB (~33.6M addresses total, 2 × 2²⁴) [Confirmed] — IEEE the IEEE MA-L registry. Note: both are MA-L, not OUI-36/MA-M — no MA-M or MA-S entry exists for this org. NOTE: IEEE's public OUI data publishes NO assignment/registration date (the IEEE MA-L registry columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools is a database artifact, not an IEEE fact.

Device types

Unknown from primary sources — no IEEE device-type field and no public captures identify specific Sankuai-MAC hardware. Plausible internal use (consistent with Meituan product lines): autonomous ground-delivery vehicles, NB-IoT bike-share locks (Meituan Bike/Mobike, Qualcomm MDM9206 + Gemalto NB-IoT), drone-delivery units, POS/restaurant terminals, datacenter/edge networking. The dual-MA-L scale (~33.6M addresses) fits fleet-scale IoT rather than a small internal network.

Security context

No CVEs, public exploits, or vendor-specific security advisories found for Sankuai/Meituan-manufactured network devices as of June 2026. Standard fleet-IoT attack-surface concerns apply in general (firmware-update integrity, cellular/WiFi credential exposure, physical access to embedded hardware); no vendor-specific threat intel located.

Special note

Third-party aggregators display dates of 2014-10-25 (84:4B:B7) and 2021-12-27 (E8:81:AB); these are database-artifact timestamps from the aggregator's own crawl/import of the IEEE OUI text file, NOT IEEE-published registration dates, and must not be presented as IEEE facts.

Analyst note

A globally-administered 84:4B:B7 / E8:81:AB address identifies genuine Sankuai-registered hardware; absence of one does not mean "not Sankuai." OUI alone does not reveal device function here — no public mapping of these prefixes to specific Meituan device models exists.
