Which company owns MAC address prefix D0:E4:8C?

MAC address prefix D0:E4:8C is registered to WITS Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D0:E4:8C has a network interface built by WITS Co., Ltd.

What is the OUI D0:E4:8C?

D0:E4:8C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to WITS Co., Ltd. It covers every address from D0:E4:8C:00:00:00 to D0:E4:8C:FF:FF:FF, or 16,777,216 addresses in total. It is also written D0-E4-8C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D0:E4:8C:00:00:00 that is D0:E4:8C — 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 WITS Co., Ltd located?

WITS Co., Ltd is listed at 10F, TechTree Yeongtong industry Center, 55, Sinwon-ro, Yeongtong-gu Suwon-si Gyeonggi-do KR 16677 in the IEEE OUI registry entry for D0:E4:8C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
