Which company owns MAC address prefix 74:A5:C2?

MAC address prefix 74:A5:C2 is registered to KYOCERA Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 74:A5:C2 has a network interface built by KYOCERA Corporation.

What is the OUI 74:A5:C2?

74:A5:C2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to KYOCERA Corporation. It covers every address from 74:A5:C2:00:00:00 to 74:A5:C2:FF:FF:FF, or 16,777,216 addresses in total. It is also written 74-A5-C2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 74:A5:C2:00:00:00 that is 74:A5:C2 — 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 KYOCERA Corporation located?

KYOCERA Corporation is listed at 3-3-31, Miyahara, Yodogawa-ku Osaka Osaka JP 532-0003 in the IEEE OUI registry entry for 74:A5:C2. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does KYOCERA Corporation own?

KYOCERA Corporation holds 4 OUI prefixes in the IEEE registry, of which 74:A5:C2 is one. A device made by KYOCERA Corporation could carry a MAC address from any of them.
