MAC address vendor

ASRock Industrial — no separate IEEE registrant (confirmed); gear surfaces under parent ASRock Incorporation's OUIs (industrial computing)

Primary prefix
00:25:22
Block
MA-L
Status
Active

Summary

// what this is
ASRock Industrial Computer is registered to MAC prefix 00:25:22 and 6 more in the IEEE OUI database. When a device's MAC address begins with 00:25:22, that block was registered by ASRock Industrial Computer — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
An ASRock OUI (e.g., BC:5F:F4) most likely indicates a consumer/enthusiast motherboard, but ASRock Industrial gear may share it; corroborate with form factor and asset data before classifying as industrial.
[ 01 ] — Context

About this vendor.

Updated  ·  Confidence: High

ASRock Industrial Computer Corp. is the industrial-computing arm and a spin-off/affiliate of ASRock, based in Taipei, Taiwan, building industrial motherboards, embedded SBCs, industrial PCs, edge-AI computing, and network appliances. It holds no separate own-name IEEE OUI — now a confirmed finding, not a pending check. Its hardware surfaces under the parent "ASRock Incorporation" registrant, which holds seven IEEE MA-L blocks: 00:25:22, 54:FB:66, 70:85:C2, 9C:6B:00, A8:A1:59, BC:5F:F4, and D0:50:99. The key analyst point is the registrant relationship: an ASRock OUI such as BC:5F:F4 most often indicates a consumer/enthusiast ASRock motherboard, but ASRock Industrial's embedded and edge gear can share those same parent blocks, and some devices instead surface under the NIC chipset vendor's OUI. For triage, corroborate an ASRock OUI with the device's form factor and asset data before classifying it as industrial rather than consumer.

Special note
Confirmed — no separate "ASRock Industrial Computer Corp." IEEE registrant. ASRock Industrial gear surfaces under the parent "ASRock Incorporation" registrant (the 7 MA-L blocks above); those blocks are shared by consumer ASRock motherboards and ASRock Industrial gear alike, and some ASRock Industrial devices instead surface under the NIC chipset vendor's OUI. IEEE publishes no assignment dates. [Confirmed]
