Which company owns MAC address prefix E4:17:D8?

MAC address prefix E4:17:D8 is registered to 8BITDO TECHNOLOGY HK LIMITED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E4:17:D8 has a network interface built by 8BITDO TECHNOLOGY HK LIMITED.

What is the OUI E4:17:D8?

E4:17:D8 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to 8BITDO TECHNOLOGY HK LIMITED. It covers every address from E4:17:D8:00:00:00 to E4:17:D8:FF:FF:FF, or 16,777,216 addresses in total. It is also written E4-17-D8.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E4:17:D8:00:00:00 that is E4:17:D8 — 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 8BITDO TECHNOLOGY HK LIMITED located?
