Which company owns MAC address prefix 00:02:FA?

MAC address prefix 00:02:FA is registered to DX Antenna Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:02:FA has a network interface built by DX Antenna Co., Ltd..

What is the OUI 00:02:FA?

00:02:FA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to DX Antenna Co., Ltd.. It covers every address from 00:02:FA:00:00:00 to 00:02:FA:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-02-FA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:02:FA:00:00:00 that is 00:02:FA — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is DX Antenna Co., Ltd. located?

DX Antenna Co., Ltd. is listed at 2-15 Hamazaki-Dori, JP in the IEEE OUI registry entry for 00:02:FA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
