Which company owns MAC address prefix AC:8B:9C?

MAC address prefix AC:8B:9C is registered to Primera Technology, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with AC:8B:9C has a network interface built by Primera Technology, Inc..

What is the OUI AC:8B:9C?

AC:8B:9C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Primera Technology, Inc.. It covers every address from AC:8B:9C:00:00:00 to AC:8B:9C:FF:FF:FF, or 16,777,216 addresses in total. It is also written AC-8B-9C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in AC:8B:9C:00:00:00 that is AC:8B:9C — 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 Primera Technology, Inc. located?

Primera Technology, Inc. is listed at 2 Carlson Parkway N, Ste 375 Plymouth MN US 55447 in the IEEE OUI registry entry for AC:8B:9C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
