Which company owns MAC address prefix FC:10:BD?

MAC address prefix FC:10:BD is registered to Control Sistematizado S.A. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with FC:10:BD has a network interface built by Control Sistematizado S.A..

What is the OUI FC:10:BD?

FC:10:BD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Control Sistematizado S.A.. It covers every address from FC:10:BD:00:00:00 to FC:10:BD:FF:FF:FF, or 16,777,216 addresses in total. It is also written FC-10-BD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in FC:10:BD:00:00:00 that is FC:10:BD — 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 Control Sistematizado S.A. located?

Control Sistematizado S.A. is listed at Cra 43 N 31 52 Medellin Antioquia CO 10101 in the IEEE OUI registry entry for FC:10:BD. This is the address the organization registered with the IEEE, which may differ from its current operating address.
