Which company owns MAC address prefix 60:81:2B?

MAC address prefix 60:81:2B is registered to Astronics Custom Control Concepts in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 60:81:2B has a network interface built by Astronics Custom Control Concepts.

What is the OUI 60:81:2B?

60:81:2B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Astronics Custom Control Concepts. It covers every address from 60:81:2B:00:00:00 to 60:81:2B:FF:FF:FF, or 16,777,216 addresses in total. It is also written 60-81-2B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 60:81:2B:00:00:00 that is 60:81:2B — 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 Astronics Custom Control Concepts located?

Astronics Custom Control Concepts is listed at 6020 S 190th ST Kent US 98032 in the IEEE OUI registry entry for 60:81:2B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
