Which company owns MAC address prefix 94:B2:CC?

MAC address prefix 94:B2:CC is registered to PIONEER CORPORATION in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 94:B2:CC has a network interface built by PIONEER CORPORATION.

What is the OUI 94:B2:CC?

94:B2:CC is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to PIONEER CORPORATION. It covers every address from 94:B2:CC:00:00:00 to 94:B2:CC:FF:FF:FF, or 16,777,216 addresses in total. It is also written 94-B2-CC.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 94:B2:CC:00:00:00 that is 94:B2:CC — 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 PIONEER CORPORATION located?

PIONEER CORPORATION is listed at 1-1 Shin-ogura Kawasaki-shi Kanagawa Prefecture JP 2120031 in the IEEE OUI registry entry for 94:B2:CC. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does PIONEER CORPORATION own?

PIONEER CORPORATION holds 3 OUI prefixes in the IEEE registry, of which 94:B2:CC is one. A device made by PIONEER CORPORATION could carry a MAC address from any of them.
