Which company owns MAC address prefix E8:C1:E8?

MAC address prefix E8:C1:E8 is registered to Shenzhen Xiao Bi En Culture Education Technology Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E8:C1:E8:00:00:00 that is E8:C1:E8 — 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.
