Which company owns MAC address prefix CC:04:7C?

MAC address prefix CC:04:7C is registered to G-WAY Microwave in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:04:7C has a network interface built by G-WAY Microwave.

What is the OUI CC:04:7C?

CC:04:7C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to G-WAY Microwave. It covers every address from CC:04:7C:00:00:00 to CC:04:7C:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-04-7C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:04:7C:00:00:00 that is CC:04:7C — 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 G-WAY Microwave located?

G-WAY Microwave is listed at 38 Leuning Street South Hackensack New Jersey US 07078 in the IEEE OUI registry entry for CC:04:7C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
