Which company owns MAC address prefix 38:08:FD?

MAC address prefix 38:08:FD is registered to Silca Spa in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 38:08:FD has a network interface built by Silca Spa.

What is the OUI 38:08:FD?

38:08:FD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Silca Spa. It covers every address from 38:08:FD:00:00:00 to 38:08:FD:FF:FF:FF, or 16,777,216 addresses in total. It is also written 38-08-FD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 38:08:FD:00:00:00 that is 38:08:FD — 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 Silca Spa located?

Silca Spa is listed at Via Podgora, 20 (Z.I.) Vittorio Veneto TV IT 31029 in the IEEE OUI registry entry for 38:08:FD. This is the address the organization registered with the IEEE, which may differ from its current operating address.
