Zhejiang Cainiao Supply Chain Management Co., Ltd — 4 prefixes (3× MA-L, 1× MA-M)

Zhejiang Cainiao Supply Chain Management Co., Ltd holds four separate IEEE MAC prefix assignments — three 24-bit MA-L blocks (24:1E:2B, FC:BC:0E, 30:63:CF) and one 28-bit MA-M block (58:C4:1E:5x) — registered across two Hangzhou, Zhejiang addresses (Xixi Center on West Wenyi Road, and a separate Fengxin Road site in Yuhang District). Multiple independent OUI blocks registered over time is normal for a large organization and is not a data conflict. The company is Cainiao Network's supply-chain-management subsidiary; Cainiao is Alibaba Group's logistics and smart-logistics arm, founded in 2013 and headquartered in Hangzhou, with a well-documented corporate footprint (D&B, Bloomberg, and its own cainiao.com property all independently corroborate the entity). Cainiao's public IoT/automation product lines — RFID logistics tags, AGV warehouse robots, sorting-arm and warehouse-automation controllers, and consumer-facing "Cainiao Box" smart delivery lockers with facial-recognition unlock — plausibly explain the need for multiple hardware-embedding MAC blocks, though no source ties any one of the four specific prefixes to a specific named product model. No MA-S (36-bit) block, no CVEs/security advisories, and no IEEE-published registration dates were found for this vendor.

Registered organization

Zhejiang Cainiao Supply Chain Management Co., Ltd (also rendered "Co.,Ltd" without a space in one MA-M record — cosmetic registry variance only) [Confirmed] — the IEEE MA-L registry, :25027, :30871; the IEEE MA-M registry

Assignments

24-1E-2B (MA-L), FC-BC-0E (MA-L), 30-63-CF (MA-L), 58-C4-1E-50/28 (MA-M) [Confirmed] — the IEEE MA-L registry, :25027, :30871; the IEEE MA-M registry; cross-confirmed the Wireshark manufacturer database, :23527, :29344, :57191

Registered addresses

(1) Block B1, XIXI center, No.588 West Wenyi Road, Xihu District, Hangzhou, Zhejiang, CN 310000 — used for 24-1E-2B, FC-BC-0E, and the MA-M block; (2) 501 Fengxin Road, Yuhang Street, Yuhang District, Hangzhou, Zhejiang, CN 310024 — used for 30-63-CF

[Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry

MA-S assignment

none found [Confirmed] — the IEEE MA-S registry (no matching entry)

Registration dates

Unknown / not recorded. IEEE's public OUI/MA-M registries carry no date field; no date is attributed to IEEE for any of the four blocks. [Confirmed — absence verified, not fabricated] — the IEEE MA-L registry, the IEEE MA-M registry

Company identity / substance

Cainiao Network's supply-chain-management subsidiary; part of Alibaba Group, founded 2013, HQ Hangzhou — well documented independently of the OUI registration [Confirmed] — https://www.dnb.com/business-directory/company-profiles.zhejiang_cainiao_supply_chain_management_co_ltd.8502b931df958943e64be0066a9d5242.html, https://www.bloomberg.com/profile/company/1291094D:CH, https://www.cainiao.com/en/index.html

Device / product context

RFID logistics tags, AGV warehouse robots, sorting-arm/warehouse-automation controllers, "Cainiao Box" smart delivery lockers with facial-recognition unlock — plausible product-line fit for 4 MAC blocks, but no source maps a specific prefix to a specific model [Likely] — https://www.cainiao.com/en/technology-iot.html, https://cainiao.medium.com/how-smart-lockers-can-resolve-last-mile-challenges-for-logistics-providers-571e15b3fc82, https://www.cnbc.com/2018/06/01/alibaba-cainaio-box-home-smart-locker-for-deliveries.html
