Which company owns MAC address prefix D8:22:F4?

MAC address prefix D8:22:F4 is registered to Avnet Silica in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D8:22:F4 has a network interface built by Avnet Silica.

What is the OUI D8:22:F4?

D8:22:F4 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Avnet Silica. It covers every address from D8:22:F4:00:00:00 to D8:22:F4:FF:FF:FF, or 16,777,216 addresses in total. It is also written D8-22-F4.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D8:22:F4:00:00:00 that is D8:22:F4 — 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 Avnet Silica located?

Avnet Silica is listed at 16 av carnot Massy FR 91349 in the IEEE OUI registry entry for D8:22:F4. This is the address the organization registered with the IEEE, which may differ from its current operating address.
