Which company owns MAC address prefix AC:E0:D6?

MAC address prefix AC:E0:D6 is registered to koreabts in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with AC:E0:D6 has a network interface built by koreabts.

What is the OUI AC:E0:D6?

AC:E0:D6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to koreabts. It covers every address from AC:E0:D6:00:00:00 to AC:E0:D6:FF:FF:FF, or 16,777,216 addresses in total. It is also written AC-E0-D6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in AC:E0:D6:00:00:00 that is AC:E0:D6 — 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 koreabts located?

koreabts is listed at 362-11, Jongga-ro, Jung-gu, Ulsan, Republic of Korea Ulsan KR 44428 in the IEEE OUI registry entry for AC:E0:D6. This is the address the organization registered with the IEEE, which may differ from its current operating address.
