Which company owns MAC address prefix 04:D6:F4?

MAC address prefix 04:D6:F4 is registered to GD Midea Air-Conditioning Equipment Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 04:D6:F4 has a network interface built by GD Midea Air-Conditioning Equipment Co.,Ltd..

What is the OUI 04:D6:F4?

04:D6:F4 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to GD Midea Air-Conditioning Equipment Co.,Ltd.. It covers every address from 04:D6:F4:00:00:00 to 04:D6:F4:FF:FF:FF, or 16,777,216 addresses in total. It is also written 04-D6-F4.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 04:D6:F4:00:00:00 that is 04:D6:F4 — 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 GD Midea Air-Conditioning Equipment Co.,Ltd. located?
