MAC address vendor

AboCom Systems Inc. — 3 prefixes (MA-L)

Primary prefix
00:12:0E
Block
MA-L
Status
Active

Summary

// what this is
AboCom Systems is registered to MAC prefix 00:12:0E and 2 more in the IEEE OUI database. When a device's MAC address begins with 00:12:0E, that block was registered by AboCom Systems — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Three corroborated OUI assignments plus FCC-documented products establish AboCom as a genuine identifiable manufacturer, not a shell registration; still, absence of confirmed CVEs is a sourced null, not a security clearance.

About this vendor.

Updated  ·  Confidence: High

A MAC address beginning with 00:12:0E, EC:F0:0E, or 00:E0:98 belongs to AboCom Systems Inc., a Taiwanese OEM manufacturer typically seen on consumer and SOHO USB Wi-Fi adapters, USB Bluetooth adapters, and Powerline Ethernet products.

AboCom holds three separate MA-L (/24) OUI registrations in the IEEE registry, all attributed to "AboCom" at Hsinchu, Taiwan addresses. The registrant address on the OUI records — 1F, No. 21, Yanfa 2nd Rd. — matches the company's own stated headquarters (R&D Rd. II, Science-Based Industrial Park, Hsinchu), confirming the OUI registrant and the live company are the same entity.

Multiple FCC ID filings corroborate real shipped products under this vendor: an 11ac 433Mbps dual-band USB adapter (MQ4AU7212), an 802.11b/g USB WLAN adapter (MQ4WUG2650-4), and Bluetooth USB adapters (MQ4UBT1K/MQ4UBT1KH), among others. This product trail, combined with three independent OUI assignments, establishes AboCom as a substantive, identifiable vendor rather than a bare single-OUI shell registration.

No IEEE registration date exists for these prefixes — the public OUI registry publishes only registry, assignment, organization name, and address, never a date. A targeted search for AboCom-branded security advisories or CVEs returned no hits; this is reported as Unknown rather than a claim that no vulnerabilities exist.
