Which company owns MAC address prefix DC:B0:58?

MAC address prefix DC:B0:58 is registered to Bürkert Werke GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:B0:58 has a network interface built by Bürkert Werke GmbH.

What is the OUI DC:B0:58?

DC:B0:58 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Bürkert Werke GmbH. It covers every address from DC:B0:58:00:00:00 to DC:B0:58:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-B0-58.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:B0:58:00:00:00 that is DC:B0:58 — 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 Bürkert Werke GmbH located?

Bürkert Werke GmbH is listed at Christian-Bürkert-Straße 13-17 Ingelfingen Baden-Württemberg DE 74653 in the IEEE OUI registry entry for DC:B0:58. This is the address the organization registered with the IEEE, which may differ from its current operating address.
