Which company owns MAC address prefix 6C:B3:4D?

MAC address prefix 6C:B3:4D is registered to SharkNinja Operating LLC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 6C:B3:4D has a network interface built by SharkNinja Operating LLC.

What is the OUI 6C:B3:4D?

6C:B3:4D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SharkNinja Operating LLC. It covers every address from 6C:B3:4D:00:00:00 to 6C:B3:4D:FF:FF:FF, or 16,777,216 addresses in total. It is also written 6C-B3-4D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 6C:B3:4D:00:00:00 that is 6C:B3:4D — 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 SharkNinja Operating LLC located?

SharkNinja Operating LLC is listed at 89 A Street, Suite 100 02494 Needham Needham MA US 02494 in the IEEE OUI registry entry for 6C:B3:4D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
