Which company owns MAC address prefix C0:02:8D?

MAC address prefix C0:02:8D is registered to WINSTAR Display CO.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C0:02:8D has a network interface built by WINSTAR Display CO.,Ltd.

What is the OUI C0:02:8D?

C0:02:8D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to WINSTAR Display CO.,Ltd. It covers every address from C0:02:8D:00:00:00 to C0:02:8D:FF:FF:FF, or 16,777,216 addresses in total. It is also written C0-02-8D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C0:02:8D:00:00:00 that is C0:02:8D — 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 WINSTAR Display CO.,Ltd located?
