Which company owns MAC address prefix BC:03:A7?

MAC address prefix BC:03:A7 is registered to MFP MICHELIN in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:03:A7 has a network interface built by MFP MICHELIN.

What is the OUI BC:03:A7?

BC:03:A7 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to MFP MICHELIN. It covers every address from BC:03:A7:00:00:00 to BC:03:A7:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-03-A7.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:03:A7:00:00:00 that is BC:03:A7 — 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 MFP MICHELIN located?

MFP MICHELIN is listed at 23 place des Carmes Dechaux Clermont-Ferrand FR 63000 in the IEEE OUI registry entry for BC:03:A7. This is the address the organization registered with the IEEE, which may differ from its current operating address.
