Which company owns MAC address prefix 44:B9:94?

MAC address prefix 44:B9:94 is registered to Douglas Lighting Controls in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 44:B9:94 has a network interface built by Douglas Lighting Controls.

What is the OUI 44:B9:94?

44:B9:94 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Douglas Lighting Controls. It covers every address from 44:B9:94:00:00:00 to 44:B9:94:FF:FF:FF, or 16,777,216 addresses in total. It is also written 44-B9-94.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 44:B9:94:00:00:00 that is 44:B9:94 — 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 Douglas Lighting Controls located?

Douglas Lighting Controls is listed at 280 - 3605 Gilmore Way Burnaby BC CA V5G4X5 in the IEEE OUI registry entry for 44:B9:94. This is the address the organization registered with the IEEE, which may differ from its current operating address.
