OUI F8:F0:C5 is an IEEE MA-L block assigned to Suzhou Kuhan Information Technologies Co., Ltd. (苏州库瀚信息科技有限公司, trading as Kuhan Tech / KuhanTech), an enterprise-storage chip company based in the Suzhou Industrial Park District, Jiangsu, China. The registry address sits at SISPARK Building 17 in that district. Kuhan is a fabless designer of enterprise SSD controllers and distributed-storage master-control SoCs; its signature part is a Multiprotocol Storage Controller (MPSC) that integrates Ethernet, RDMA (RoCE/iWARP), InfiniBand, NVMe, PCIe and flash (ONFI) interfaces on a single die. Because of that product focus, devices presenting this OUI are most plausibly enterprise storage controllers, HBA/SmartNIC-class adapters, or NVMe-oF storage appliances rather than consumer or IoT hardware — though the IEEE record itself names no device type, so any device-type read is an inference from the company's patents and business profile, not a registry fact. The block is a 24-bit MA-L (~16 million addresses). IEEE publishes no registration date for MA-L assignments; a "16 August 2022" date seen on third-party lookup tools is a database artifact, not an IEEE first-party fact, and is not recorded here as authoritative.

- No IEEE date
- IEEE's public OUI data (oui.csv columns: Registry, Assignment, Organization Name, Organization Address) publishes NO registration date. A "16 August 2022" date on maclookup.app is a third-party database artifact, not an IEEE fact — not recorded as authoritative.

- Device types
- most plausibly enterprise storage controllers / HBA / SmartNIC-class adapters / NVMe-oF storage appliances, derived from Kuhan's Multiprotocol Storage Controller (MPSC) SoC integrating Ethernet/RDMA/NVMe/InfiniBand/PCIe/ONFI. Not published in the IEEE record; inferred from patents + business profile.

- Industry
- enterprise data-center storage silicon (fabless SSD/distributed-storage controller design) [Likely] — https://www.trendforce.com/news/2024/10/30/news-what-are-chinese-enterprise-ssd-manufacturers-competing-for/ ; https://www.kuhantech.com/
- Security context
- no public CVEs, threat-intel reports, or known-bad-MAC-list entries found for this OUI or vendor; enterprise storage segment, so the realistic threat surface is supply-chain/firmware integrity rather than consumer IoT vectors. No security flags at this time. [Likely] — single-angle web survey; no contradicting source
- Analyst note
- F8:F0:C5 on a globally-administered address identifies genuine Kuhan-controller hardware for asset classification, but the specific device behind it is an inference from product focus, not a registry-stated device type.
