MAC address vendor

Rayson Technology Co., Ltd. — 2 prefixes (MA-L)

Primary prefix
00:12:6F
Block
MA-L
Status
Active

Summary

// what this is
Rayson Technology is registered to MAC prefix 00:12:6F and 1 more in the IEEE OUI database. When a device's MAC address begins with 00:12:6F, that block was registered by Rayson Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Two independently-registered OUI blocks to the same registrant name/address, plus FCC equipment-authorization filings (grantee code QWO) for four named Bluetooth/Wi-Fi modules, together establish verifiable company substance beyond a bare single-OUI registration — this entry does not qualify for shell abstention.

About this vendor.

Updated  ·  Confidence: Medium

Rayson Technology Co., Ltd. holds two MA-L OUI blocks — 00:12:6F and 54:B7:E5 — both registered to the identical Hsinchu, Taiwan address (1F No.9 R&D Rd. II, Science-Based Industrial Park, Hsin-Chu, TW 300), a repeated-registrant pattern that on its own signals an operating company rather than a one-off registration. Independent web research corroborates this: Rayson is a real, findable Taiwanese electronics maker that self-describes as founded in 1990, headquartered in the same Hsinchu science park, with additional manufacturing in Shenzhen, China and a Hong Kong logistics presence. Its core business is wired/wireless communications hardware, concentrated on Bluetooth/BLE and Wi-Fi OEM/ODM radio modules aimed at IoT, consumer, and industrial integrators — components embedded inside third-party end products rather than standalone network appliances sold under Rayson's own brand. FCC equipment-authorization filings under grantee code QWO name several specific Rayson modules (BTM-22X/BTM222, BTM-641, QS9322-PLCS, SWA51), giving concrete, verifiable device-type corroboration beyond the bare registry listing. No vendor-specific CVEs or security advisories turned up in a light search; because Rayson ships embeddable radio modules rather than end-user appliances, any given device's security posture depends on the OEM integrator's firmware and configuration, not on Rayson itself. A third-party lookup site (maclookup.app) surfaces "registration"/"last updated" dates for 00:12:6F, but these are database-ingestion artifacts, not IEEE-published assignment dates, and are correctly excluded from this record.

date_registered
Unknown — IEEE's public OUI registry publishes no assignment/registration date; a third-party site (maclookup.app) shows ingestion timestamps for 00:12:6F, which are database artifacts, not IEEE facts, and are not recorded here [Confirmed] — https://maclookup.app/macaddress/00126F
iana_reference
Not applicable to OUI/MAC registry entries; left null [Confirmed]
Security context
no vendor-specific CVEs or advisories found; as an OEM/ODM module vendor, end-device security depends on the integrator, not Rayson [Unknown] — negative search result, no citation
Company substance assessment
two independently-listed OUI blocks to the same registrant plus FCC-filed named products establish verifiable substance beyond a bare single-OUI shell [Confirmed] — the IEEE MA-L registry, FCC filings above
