Which company owns MAC address prefix EC:63:ED?

MAC address prefix EC:63:ED is registered to Hyundai Autoever Corp. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:63:ED has a network interface built by Hyundai Autoever Corp..

What is the OUI EC:63:ED?

EC:63:ED is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Hyundai Autoever Corp.. It covers every address from EC:63:ED:00:00:00 to EC:63:ED:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-63-ED.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:63:ED:00:00:00 that is EC:63: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 Hyundai Autoever Corp. located?

Hyundai Autoever Corp. is listed at 38, Teheran-ro 114-gil Gangnam-gu, Seoul KR 06176 in the IEEE OUI registry entry for EC:63:ED. This is the address the organization registered with the IEEE, which may differ from its current operating address.
