Which company owns MAC address prefix EC:8E:AD?

MAC address prefix EC:8E:AD is registered to DLX in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:8E:AD has a network interface built by DLX.

What is the OUI EC:8E:AD?

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

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:8E:AD:00:00:00 that is EC:8E:AD — 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 DLX located?

DLX is listed at #401, Seoil B/D,1359-45 Seocho2-dong Seoul KR 137-863 in the IEEE OUI registry entry for EC:8E:AD. This is the address the organization registered with the IEEE, which may differ from its current operating address.

DLX

MAC address prefix EC:8E:AD is registered to DLX in the IEEE OUI registry. Any device whose MAC address begins with EC:8E:AD has a network interface built by DLX. This prefix (the OUI, or Organizationally Unique Identifier) is assigned by the IEEE and is the first three octets of the address — it covers every MAC from EC:8E:AD:00:00:00 to EC:8E:AD:FF:FF:FF.
