Which company owns MAC address prefix 54:7E:1A?

MAC address prefix 54:7E:1A is registered to Kaon Group Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 54:7E:1A has a network interface built by Kaon Group Co., Ltd..

What is the OUI 54:7E:1A?

54:7E:1A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Kaon Group Co., Ltd.. It covers every address from 54:7E:1A:00:00:00 to 54:7E:1A:FF:FF:FF, or 16,777,216 addresses in total. It is also written 54-7E-1A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 54:7E:1A:00:00:00 that is 54:7E:1A — 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 Kaon Group Co., Ltd. located?

Kaon Group Co., Ltd. is listed at 884-3, Seongnam-daero, Bundang-gu Seongnam-si Gyeonggi-do KR 13517 in the IEEE OUI registry entry for 54:7E:1A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
