Which company owns MAC address prefix E0:14:3E?

MAC address prefix E0:14:3E is registered to Modoosis Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:14:3E has a network interface built by Modoosis Inc..

What is the OUI E0:14:3E?

E0:14:3E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Modoosis Inc.. It covers every address from E0:14:3E:00:00:00 to E0:14:3E:FF:FF:FF, or 16,777,216 addresses in total. It is also written E0-14-3E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:14:3E:00:00:00 that is E0:14:3E — 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 Modoosis Inc. located?

Modoosis Inc. is listed at #302, Samil Bldg., 656-282 Seoul KR 133-110 in the IEEE OUI registry entry for E0:14:3E. This is the address the organization registered with the IEEE, which may differ from its current operating address.
