Which company owns MAC address prefix 54:03:84?

MAC address prefix 54:03:84 is registered to Hongkong Nano IC Technologies Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 54:03:84 has a network interface built by Hongkong Nano IC Technologies Co., Ltd.

What is the OUI 54:03:84?

54:03:84 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Hongkong Nano IC Technologies Co., Ltd. It covers every address from 54:03:84:00:00:00 to 54:03:84:FF:FF:FF, or 16,777,216 addresses in total. It is also written 54-03-84.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 54:03:84:00:00:00 that is 54:03:84 — 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.
