Which company owns MAC address prefix EC:2E:4E?

MAC address prefix EC:2E:4E is registered to HITACHI-LG DATA STORAGE INC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:2E:4E has a network interface built by HITACHI-LG DATA STORAGE INC.

What is the OUI EC:2E:4E?

EC:2E:4E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to HITACHI-LG DATA STORAGE INC. It covers every address from EC:2E:4E:00:00:00 to EC:2E:4E:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-2E-4E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:2E:4E:00:00:00 that is EC:2E:4E — 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 HITACHI-LG DATA STORAGE INC located?

HITACHI-LG DATA STORAGE INC is listed at 4F, MSC CENTER BLDG., 22-23 KAIGAN 3-CHOME, MINATO-KU, TOKYO TOKYO JP 108-0022 in the IEEE OUI registry entry for EC:2E:4E. This is the address the organization registered with the IEEE, which may differ from its current operating address.
