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

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

What is the OUI D0:B0:DF?

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

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D0:B0:DF:00:00:00 that is D0:B0:DF — 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 Mimosa Networks located?

Mimosa Networks is listed at 3150 Coronado Dr Santa Clara CA US 95054 in the IEEE OUI registry entry for D0:B0:DF. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Mimosa Networks own?

Mimosa Networks holds 6 OUI prefixes in the IEEE registry, of which D0:B0:DF is one. A device made by Mimosa Networks could carry a MAC address from any of them.
