Which company owns MAC address prefix D8:25:B0?

MAC address prefix D8:25:B0 is registered to Rockeetech Systems Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D8:25:B0 has a network interface built by Rockeetech Systems Co.,Ltd..

What is the OUI D8:25:B0?

D8:25:B0 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Rockeetech Systems Co.,Ltd.. It covers every address from D8:25:B0:00:00:00 to D8:25:B0:FF:FF:FF, or 16,777,216 addresses in total. It is also written D8-25-B0.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D8:25:B0:00:00:00 that is D8:25:B0 — 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.
