Dawning holds at least one MA-L block — confirmed prefix E8:61:1F — registered as "Dawning Information Industry Co., Ltd" at No. 15 Huake Street, Hi-Tech Zone, Tianjin, China. The brand is "Sugon" (曙光); the company originated as "Dawning," a spin-off from the Chinese Academy of Sciences. These OUIs appear on rackmount servers, supercomputer and HPC nodes, storage systems, and cloud/datacenter hardware. On the regulatory side, stated factually: the U.S. Department of Commerce BIS added Sugon to the Entity List effective 2019-06-24 (Federal Register 84 FR 29371, Vol. 84 No. 121), with nine aliases including "Dawning, Dawning Information Industry, Tianjin Shuguang Computer Industry," and BIS stated Sugon "has publicly acknowledged a variety of military end uses and end users of its high-performance computers"; separately, the U.S. Department of Defense's Section 1260H list, published 2022-10-05, names "Dawning Information Industry Co., Ltd. (Sugon)" among Chinese military companies. The key analyst point is that an E8:61:1F OUI indicates Sugon/Dawning server or HPC hardware — a noteworthy asset to flag given the export-control and military-list context, stated neutrally. For triage, corroborate the device identity before acting.
