Which company owns MAC address prefix DC:D0:F7?

MAC address prefix DC:D0:F7 is registered to Bentek Systems Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:D0:F7 has a network interface built by Bentek Systems Ltd..

What is the OUI DC:D0:F7?

DC:D0:F7 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Bentek Systems Ltd.. It covers every address from DC:D0:F7:00:00:00 to DC:D0:F7:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-D0-F7.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:D0:F7:00:00:00 that is DC:D0:F7 — 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 Bentek Systems Ltd. located?

Bentek Systems Ltd. is listed at 315 - 3750 46th Ave. SE Calgary AB CA T2B 0L1 in the IEEE OUI registry entry for DC:D0:F7. This is the address the organization registered with the IEEE, which may differ from its current operating address.
