Which company owns MAC address prefix D0:B0:CD?

MAC address prefix D0:B0:CD is registered to Moen in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D0:B0:CD has a network interface built by Moen.

What is the OUI D0:B0:CD?

D0:B0:CD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Moen. It covers every address from D0:B0:CD:00:00:00 to D0:B0:CD:FF:FF:FF, or 16,777,216 addresses in total. It is also written D0-B0-CD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D0:B0:CD:00:00:00 that is D0:B0:CD — 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 Moen located?

Moen is listed at 25300 Al Moen Dr North Olmstead OH US 44070-8022 in the IEEE OUI registry entry for D0:B0:CD. This is the address the organization registered with the IEEE, which may differ from its current operating address.
