What is the OUI D8:08:F5?

D8:08:F5 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Arcadia Networks Co. Ltd.. It covers every address from D8:08:F5:00:00:00 to D8:08:F5:FF:FF:FF, or 16,777,216 addresses in total. It is also written D8-08-F5.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D8:08:F5:00:00:00 that is D8:08: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 Arcadia Networks Co. Ltd. located?

Arcadia Networks Co. Ltd. is listed at Cheung Sha Wan 5-B FL Kowloon HK 0633 in the IEEE OUI registry entry for D8:08:F5. This is the address the organization registered with the IEEE, which may differ from its current operating address.
