Qingdao Haier Technology Co.,Ltd — 22 prefixes (MA-L)

Qingdao Haier Technology Co.,Ltd is a technology entity of the Haier Group, the Qingdao-founded (1984) Chinese home-appliance and consumer-electronics maker whose listed appliance arm, Haier Smart Home, covers the Haier, Casarte, Leader, GE Appliances, Fisher & Paykel, Aqua, Candy, and Evo brands. Across the IEEE MA-L registry this organization holds 22 distinct 24-bit OUI blocks under a single name with only punctuation/spacing variants ("Qingdao HaierTechnology Co.,Ltd", "Qingdao Haier Technology Co.Ltd"), so consolidating them into one vendor entry is far more useful than minting 22 near-identical per-prefix pages. The blocks carry two registry addresses — Building A01 and Building C01, both at Haier Information Park, No.1 Haier Road, Qingdao, Shandong 266101 — plus one outlier (34:29:EF) at Laoshan District, postal 266000. These allocations back networked smart appliances (air conditioners, refrigerators, washers/dryers, microwaves) connected through Haier's U+ IoT cloud in China and the SmartHQ / hOn companion apps internationally; Haier has used Broadcom's WICED embedded Wi-Fi platform for appliance connectivity. Two data-quality cautions apply. First, this exact slug must not absorb the related-but-distinct registrants "Qingdao Haier Intelligent Home Appliance Technology Co.,Ltd" (2C:37:C5), "Qingdao Haier Multimedia Limited." (D0:58:C0), or "QING DAO HAIER TELECOM CO.,LTD." — those are separate OUI entries. Second, IEEE publishes no assignment dates; any "registered" date on third-party lookup tools (e.g. maclookup.app's "28 December 2017") is a database artifact, not an IEEE fact.

IEEE assignment

Security context

Unknown — no vendor- or device-specific CVE for Qingdao Haier Technology or Haier smart appliances found in this pass (NVD keyword search + general web returned only class-wide consumer-IoT risk literature, none Haier-attributed); recorded as a sourced null, not "no known vulnerabilities" and not an invented CVE. Deeper pass (NVD UI, CISA KEV, CNVD/CN-CERT) not exhausted.

Third-party date caveat

maclookup.app reports "registered 28 December 2017 / updated 24 December 2024" for this OUI grouping — this is maclookup.app's own scrape/update artifact, NOT an IEEE registration date; left blank/Unknown here. [Confirmed artifact] — maclookup.app/vendors/qingdao-haier-technology-co-ltd

Analyst note

A globally-administered Qingdao Haier Technology OUI on a wired appliance interface reliably identifies genuine Haier smart-appliance hardware; but many of these devices join Wi-Fi and consumer IoT stacks may randomize MACs, so absence of the OUI does not mean "not Haier." Use registry name variants when matching, and keep the sibling Haier registrants separate.
