What is the OUI D0:25:16?

D0:25:16 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to MERCURY COMMUNICATION TECHNOLOGIES CO.,LTD.. It covers every address from D0:25:16:00:00:00 to D0:25:16:FF:FF:FF, or 16,777,216 addresses in total. It is also written D0-25-16.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D0:25:16:00:00:00 that is D0:25:16 — 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.
