Ubee Interactive — 14 + 3 prefixes (MA-L); cable/broadband CPE, OUI = brand / ISP-supplied (Ambit Microsystems lineage)

Ubee's MAC footprint spans two IEEE registrants that should be aliased to one lineage: "Ubee Interactive Co., Limited" (14 blocks, about 235 million addresses) and the legacy "Ambit Microsystems Corporation" (3 blocks). The full Ubee set is 0C:B9:37, 1C:83:EC, 2C:8A:C7, 54:49:FC, 58:76:B3, 5C:53:C3, 5C:A9:31, 64:7C:34, 6C:38:A1, 94:4E:5B, A0:ED:6D, A4:CF:D2, D8:78:7F and F0:D5:06; the Ambit blocks are 00:02:8A, 00:0E:9B and 00:D0:59. 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.

IEEE assignment

"Ubee Interactive Co., Limited" (14) + legacy "Ambit Microsystems Corporation" (3) = 17 MA-L blocks [Confirmed] — IEEE the IEEE MA-L registry

Registry / block size

MA-L only; Ubee 14 blocks (~235M) + Ambit 3 blocks; zero MA-M / MA-S entries for either registrant [Confirmed] — IEEE the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry

HQ / country

Ubee — Flat/RM 1202, 12/F, AT Tower, 180 Electric Road, North Point, Hong Kong (differs from US operations; F0:D5:06 and 1C:83:EC instead list Unit 2703A, 27/F, 148 Electric Road — an office move or second registered address); Ambit — 5F-1, 5 Hsin-An Road, Hsinchu, Taiwan

[Confirmed] — IEEE the IEEE MA-L registry

Registrant-variant note

one Ubee row (1C:83:EC) mis-spells the org as "Ubee Interactive co, Limited." — a registry data-entry variant of the same entity, counted in the 14. [Confirmed] — IEEE the IEEE MA-L registry

Company status

active; Ubee descended from Ambit Microsystems (a Foxconn/Hon Hai-related CPE maker) [Likely] — maclookup.app, corporate

Device types

DOCSIS cable modems, residential gateways, DSL/fiber CPE [Confirmed] — maclookup.app

Notable products

Ubee-branded and carrier-branded cable modems/gateways, common in North American cable deployments

Verified prefixes (legacy Ambit Microsystems Corporation, all MA-L)

00:02:8A, 00:0E:9B, 00:D0:59 [Confirmed] — IEEE the IEEE MA-L registry

Do-not-conflate

"UbeeAirWalk, Inc." (00:0C:9D, Richardson TX, US) is a distinct US-registered entity and is NOT included here; "Shenzhen Duubee Intelligent Technologies" is an unrelated substring match [Confirmed] — IEEE the IEEE MA-L registry

Special note

ISP-supplied-CPE case. Ubee OUIs commonly identify ISP-deployed cable CPE; legacy "Ambit Microsystems" is a separately-named historical registrant mapped to the same lineage (a disclosed alias, not a registrant match). The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]

Analyst note

A Ubee or Ambit OUI on a home network almost always means an ISP-supplied cable modem/gateway; map to the deploying cable operator.
