Which company owns MAC address prefix D4:9E:6D?

MAC address prefix D4:9E:6D is registered to Wuhan Zhongyuan Huadian Science & Technology Co., in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D4:9E:6D has a network interface built by Wuhan Zhongyuan Huadian Science & Technology Co.,.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D4:9E:6D:00:00:00 that is D4:9E:6D — 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.
