MAC address vendor

MiTAC Computing Technology Corporation — 2 prefixes (MA-L)

Primary prefix
14:84:30
Block
MA-L
Status
Active

Summary

// what this is
MiTAC Computing Technology is registered to MAC prefix 14:84:30 and 1 more in the IEEE OUI database. When a device's MAC address begins with 14:84:30, that block was registered by MiTAC Computing Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
A MAC starting 4C:38:D5 or 14:84:30 is a direct-vendor signal for MiTAC Computing Technology Corporation specifically — both are full /24 blocks, not a shared IEEE-RA base. Device-model attribution beyond 'MiTAC server-related hardware' is inference from the product line, not a directly sourced fact.

About this vendor.

Updated  ·  Confidence: High  ·  7 sources  ·  How this page is checked

A MAC address starting with 4C:38:D5 or 14:84:30 belongs to MiTAC Computing Technology Corporation, a Taiwan-based server ODM/OEM headquartered in Hsinchu Science Park. Both are full, non-shared MA-L (/24) OUI blocks registered directly to the company, so hardware carrying either prefix traces to MiTAC Computing rather than to a pooled IEEE-RA base.

MiTAC Computing Technology Corp. was spun off September 1, 2014 from MiTAC International Corporation's Cloud Computing Business Group, entered the server-ODM business in 1999, acquired Tyan Computer in 2007, and co-founded the OpenPOWER Consortium with IBM, Google, Mellanox, and NVIDIA. Its parent, MiTAC Holdings Corporation, trades on the Taiwan Stock Exchange (TSE: 3706).

The company's current product lines cover AI/HPC/GPU, cloud, OCP, blade, and rack servers, and it publishes first-party BMC/IPMI firmware documentation — consistent with these OUIs appearing on server mainboard NICs and out-of-band management ports, though no source ties either prefix to a specific model. Several related but legally distinct Mitac entities hold separate, older OUI blocks under different names and addresses.

IEEE's public OUI registry publishes no assignment date for either block; third-party lookup tools that display one are reading their own ingestion timestamp, not an IEEE fact. No CVE specific to MiTAC Computing's BMC/IPMI firmware or to these two prefixes was found in NVD as of an August 2026 search.

Security context
no CVE specific to MiTAC Computing's BMC/IPMI firmware or to these two prefixes found in NVD as of an August 2026 search; contemporaneous BMC CVEs located in the same search (CVE-2024-36435, CVE-2024-54085) are Supermicro/AMI-specific, not MiTAC [Likely] — nvd.nist.gov/vuln/detail/CVE-2025-55182
Analyst note
a MAC starting 4C:38:D5 or 14:84:30 is a direct-vendor signal for MiTAC Computing Technology Corporation specifically, since both are full /24 blocks rather than a shared IEEE-RA base like 70:B3:D5; device-model attribution beyond "MiTAC server-related hardware" is inference from the product line, not a directly sourced fact
