Ubee's MAC footprint spans two IEEE registrants that should be aliased to one lineage: "Ubee Interactive Co., Limited" (13 blocks, about 218.1 million addresses) and the legacy "Ambit Microsystems Corporation" (2 blocks). Verified samples include 0C:B9:37, 1C:83:EC, 64:7C:34, A4:CF:D2, and D8:78:7F (Ubee), plus 00:02:8A and 00:0E:9B with a further legacy 00:D0:59 (Ambit). The Ubee registration address is Flat/RM 1202, 12/F, AT Tower, 180 Electric Road, North Point, Hong Kong — note this differs from Ubee's US operations — while the Ambit address is 5F-1, 5 Hsin-An Road, Taiwan. These OUIs appear on DOCSIS cable modems, residential gateways, and DSL/fiber CPE, common in North American cable deployments. Ubee descended from Ambit Microsystems, a Foxconn/Hon Hai-related CPE maker, so the Ambit blocks map to the same lineage. The key analyst point is the ISP-supplied-CPE pattern. For triage, a Ubee or Ambit OUI on a home network almost always means an ISP-supplied cable modem or gateway — map it to the deploying cable operator.

- Special note
- ISP-supplied-CPE case. Ubee OUIs commonly identify ISP-deployed cable CPE; legacy "Ambit Microsystems" is a related historical registrant to map to the same lineage. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
