Which company owns MAC address prefix 94:3E:E4?

MAC address prefix 94:3E:E4 is registered to WiSA Technologies Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 94:3E:E4 has a network interface built by WiSA Technologies Inc.

What is the OUI 94:3E:E4?

94:3E:E4 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to WiSA Technologies Inc. It covers every address from 94:3E:E4:00:00:00 to 94:3E:E4:FF:FF:FF, or 16,777,216 addresses in total. It is also written 94-3E-E4.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 94:3E:E4:00:00:00 that is 94:3E:E4 — 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 WiSA Technologies Inc located?

WiSA Technologies Inc is listed at 15268 Northwest Greenbrier Parkway Beaverton OR US 97006 in the IEEE OUI registry entry for 94:3E:E4. This is the address the organization registered with the IEEE, which may differ from its current operating address.
