SONoC Corp. — 84:AA:A4 (MA-L)

The OUI 84:AA:A4 is registered to SONoC Corp., a Taiwan-based company operating from 8F-3, No. 1071, Zhongzheng Road, Taoyuan District, Taoyuan City 330. The assignment is a full MA-L block (a 24-bit prefix covering 84:AA:A4:00:00:00 through 84:AA:A4:FF:FF:FF, roughly 16.7M addresses) confirmed by the bundled IEEE registry snapshot and two independent third-party OUI aggregators. SONoC (trading as "SONoC Taiwan" at sonoc.tw) operates as a technology retailer and platform distributor for decentralized-network and blockchain-incentivized edge hardware rather than as a silicon or firmware manufacturer; device lines associated with the brand include the Roam Rainier Max60 decentralized Wi-Fi hotspot (OpenRoaming on Solana), RAK Hotspot V2 LoRaWAN/Helium gateways, the Hivemapper Bee mapping dashcam, and SenseCAP M1 environmental sensors. The primary device category is wireless networking hardware paired with cryptocurrency reward firmware. No CVEs or public security advisories were found for SONoC Corp. or its product lines as of June 2026. As with all OUI work, no assignment date is recorded: IEEE publishes none, and the 2022-06-08 timestamp surfaced by maclookup.app is a database-sync artifact, not an IEEE registration date.

IEEE assignment

84:AA:A4 → SONoC Corp. [Confirmed] — the IEEE MA-L registry line 492; cross-confirmed https://api.maclookup.app/v2/macs/84:AA:A4 and https://www.macvendorlookup.com/api/v1/84:AA:A4

Registry / block size

MA-L (24-bit OUI; 84:AA:A4:00:00:00–84:AA:A4:FF:FF:FF, ~16.7M addresses) [Confirmed] — the IEEE MA-L registry line 492; https://api.maclookup.app/v2/macs/84:AA:A4. NOTE: IEEE public OUI data publishes NO assignment/registration date; any "date registered" on third-party tools is a database artifact, not an IEEE fact.

Security context

No CVEs or public security advisories found for SONoC Corp. or its device lines as of June 2026. Elevated contextual considerations apply by product category: decentralized/blockchain-incentivized hotspots (Roam, RAK) share home/business internet with unknown external users (open-hotspot traffic-isolation risks); on-device blockchain node functions expand the network-accessible attack surface vs. a conventional AP; the Hivemapper Bee records GPS-tagged driving routes (location-data privacy risk).

Allocated date

Unknown — IEEE publishes no registration dates for OUI/MAC assignments; the 2022-06-08 maclookup.app "updated" field is a third-party DB-sync artifact, not an IEEE assignment date [Unknown] — https://api.maclookup.app/v2/macs/84:AA:A4

Analyst note

A single physical device under this OUI may not be SONoC-manufactured — SONoC distributes/retails third-party blockchain hardware, so the OUI identifies the registrant of record rather than a uniform device family.
