Which company owns MAC address prefix AC:4A:FE?

MAC address prefix AC:4A:FE is registered to Hisense Broadband Multimedia Technology Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with AC:4A:FE has a network interface built by Hisense Broadband Multimedia Technology Co.,Ltd..

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in AC:4A:FE:00:00:00 that is AC:4A:FE — 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.
