What is the OUI C8:48:F5?

C8:48:F5 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to MEDISON Xray Co., Ltd. It covers every address from C8:48:F5:00:00:00 to C8:48:F5:FF:FF:FF, or 16,777,216 addresses in total. It is also written C8-48-F5.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C8:48:F5:00:00:00 that is C8:48:F5 — 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 MEDISON Xray Co., Ltd located?
