Which company owns MAC address prefix AC:96:5B?

MAC address prefix AC:96:5B is registered to Lucid Motors in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with AC:96:5B has a network interface built by Lucid Motors.

What is the OUI AC:96:5B?

AC:96:5B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Lucid Motors. It covers every address from AC:96:5B:00:00:00 to AC:96:5B:FF:FF:FF, or 16,777,216 addresses in total. It is also written AC-96-5B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in AC:96:5B:00:00:00 that is AC:96:5B — 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 Lucid Motors located?

Lucid Motors is listed at 7373 Gateway Blvd Newark CA US 94560 in the IEEE OUI registry entry for AC:96:5B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
