Which company owns MAC address prefix 68:58:C5?

MAC address prefix 68:58:C5 is registered to ZF TRW Automotive in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 68:58:C5 has a network interface built by ZF TRW Automotive.

What is the OUI 68:58:C5?

68:58:C5 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ZF TRW Automotive. It covers every address from 68:58:C5:00:00:00 to 68:58:C5:FF:FF:FF, or 16,777,216 addresses in total. It is also written 68-58-C5.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 68:58:C5:00:00:00 that is 68:58:C5 — 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 ZF TRW Automotive located?

ZF TRW Automotive is listed at 12001 Tech Center Drive Livonia MI US 48150 in the IEEE OUI registry entry for 68:58:C5. This is the address the organization registered with the IEEE, which may differ from its current operating address.
