Which company owns MAC address prefix E0:49:ED?

MAC address prefix E0:49:ED is registered to Audeze LLC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:49:ED has a network interface built by Audeze LLC.

What is the OUI E0:49:ED?

E0:49:ED is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Audeze LLC. It covers every address from E0:49:ED:00:00:00 to E0:49:ED:FF:FF:FF, or 16,777,216 addresses in total. It is also written E0-49-ED.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:49:ED:00:00:00 that is E0:49:ED — 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 Audeze LLC located?

Audeze LLC is listed at 3410 S Susan st Santa Ana CA US 92704 in the IEEE OUI registry entry for E0:49:ED. This is the address the organization registered with the IEEE, which may differ from its current operating address.
