Which company owns MAC address prefix D8:A6:FD?

MAC address prefix D8:A6:FD is registered to Ghost Autonomy Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D8:A6:FD has a network interface built by Ghost Autonomy Inc..

What is the OUI D8:A6:FD?

D8:A6:FD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ghost Autonomy Inc.. It covers every address from D8:A6:FD:00:00:00 to D8:A6:FD:FF:FF:FF, or 16,777,216 addresses in total. It is also written D8-A6-FD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D8:A6:FD:00:00:00 that is D8:A6:FD — 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 Ghost Autonomy Inc. located?

Ghost Autonomy Inc. is listed at 800 California St. Suite 200 Mountain View CA US 94041 in the IEEE OUI registry entry for D8:A6:FD. This is the address the organization registered with the IEEE, which may differ from its current operating address.
