MAC address vendor

MiTAC International Corp — 2 prefixes (MA-L)

Primary prefix
00:22:4D
Block
MA-L
Status
Active

Summary

// what this is
MiTAC International is registered to MAC prefix 00:22:4D and 1 more in the IEEE OUI database. When a device's MAC address begins with 00:22:4D, that block was registered by MiTAC International — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
A MAC beginning 00:22:4D or 00:40:D0 is a direct, dedicated MiTAC International Corp assignment (not a shared-base inference). The MiTAC corporate family holds at least four separately-named OUI registrants; a prefix under any sibling name should not be attributed to MiTAC International Corp specifically without checking which exact registrant name holds that prefix.

About this vendor.

Updated  ·  Confidence: High  ·  9 sources  ·  How this page is checked

A MAC address starting with 00:22:4D or 00:40:D0 belongs to MiTAC International Corp, a Taiwanese electronics manufacturer, and is typically seen on GPS/car-navigation devices, dashcams, or automotive infotainment hardware sold under the Mio, Magellan, and Navman brands.

MiTAC International Corp traces to a 1982 founding in Hsinchu Science Park, Taiwan, as part of the MiTAC-Synnex Group. In 2013 the group reorganized into MiTAC Holdings Corp (Taiwan Stock Exchange code 3706), which today spans MiTAC International Corp alongside related-but-distinct entities, including MiTAC Computing Technology Corporation, spun off in 2014 to carry the server and motherboard (Tyan) business under its own separate OUI assignments.

Both 00:22:4D and 00:40:D0 are independently assigned MA-L /24 blocks, not sub-allocations of a shared IEEE Registration Authority base, so a device presenting either prefix is a direct MiTAC International Corp registration rather than an inference across thousands of unrelated registrants.

The prefix-to-registrant mapping is confirmed directly against the cached first-party IEEE registry: the IEEE MA-L registry 00224D and the IEEE MA-L registry 0040D0 both carry the registrant MITAC INTERNATIONAL CORP. Three independent third-party MAC lookup aggregators corroborate the same registrant name and address. No CVE or malware association was found tied specifically to this registrant as of an August 2026 search.
