Which company owns MAC address prefix C4:BB:89?

MAC address prefix C4:BB:89 is registered to Shanghai High-Flying Electronics Technology Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C4:BB:89 has a network interface built by Shanghai High-Flying Electronics Technology Co.,Ltd.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C4:BB:89:00:00:00 that is C4:BB:89 — 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.

How many MAC prefixes does Shanghai High-Flying Electronics Technology Co.,Ltd own?

Shanghai High-Flying Electronics Technology Co.,Ltd holds 3 OUI prefixes in the IEEE registry, of which C4:BB:89 is one. A device made by Shanghai High-Flying Electronics Technology Co.,Ltd could carry a MAC address from any of them.
