Which company owns MAC address prefix E0:69:3A?

MAC address prefix E0:69:3A is registered to Innophase Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:69:3A has a network interface built by Innophase Inc..

What is the OUI E0:69:3A?

E0:69:3A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Innophase Inc.. It covers every address from E0:69:3A:00:00:00 to E0:69:3A:FF:FF:FF, or 16,777,216 addresses in total. It is also written E0-69-3A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:69:3A:00:00:00 that is E0:69:3A — 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 Innophase Inc. located?

Innophase Inc. is listed at 6815 Flanders Drive Suite 150 San Diego CA US 92121 in the IEEE OUI registry entry for E0:69:3A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
