Which company owns MAC address prefix AC:14:61?

MAC address prefix AC:14:61 is registered to ATAW Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with AC:14:61 has a network interface built by ATAW Co., Ltd..

What is the OUI AC:14:61?

AC:14:61 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ATAW Co., Ltd.. It covers every address from AC:14:61:00:00:00 to AC:14:61:FF:FF:FF, or 16,777,216 addresses in total. It is also written AC-14-61.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in AC:14:61:00:00:00 that is AC:14:61 — 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 ATAW Co., Ltd. located?

ATAW Co., Ltd. is listed at Dongan-gu Pyeongchon-dong 126-1 Anyang-si Gyeonggi-do KR 431-755 in the IEEE OUI registry entry for AC:14:61. This is the address the organization registered with the IEEE, which may differ from its current operating address.
