Private
MAC address prefix BC:C2:D9 is registered to Private in the IEEE OUI registry. Any device whose MAC address begins with BC:C2:D9 has a network interface built by Private. This prefix (the OUI, or Organizationally Unique Identifier) is assigned by the IEEE and is the first three octets of the address — it covers every MAC from BC:C2:D9:00:00:00 to BC:C2:D9:FF:FF:FF.

FAQ
- Which company owns MAC address prefix BC:C2:D9?
- MAC address prefix BC:C2:D9 is registered to Private in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:C2:D9 has a network interface built by Private.
- What is the OUI BC:C2:D9?
- BC:C2:D9 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Private. It covers every address from BC:C2:D9:00:00:00 to BC:C2:D9:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-C2-D9.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in BC:C2:D9:00:00:00 that is BC:C2:D9 — 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.
