Which company owns MAC address prefix 24:B6:B8?

MAC address prefix 24:B6:B8 is registered to FRIEM SPA in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 24:B6:B8 has a network interface built by FRIEM SPA.

What is the OUI 24:B6:B8?

24:B6:B8 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to FRIEM SPA. It covers every address from 24:B6:B8:00:00:00 to 24:B6:B8:FF:FF:FF, or 16,777,216 addresses in total. It is also written 24-B6-B8.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 24:B6:B8:00:00:00 that is 24:B6:B8 — 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 FRIEM SPA located?

FRIEM SPA is listed at Via Edison 1 Segrate Milano IT 20090 in the IEEE OUI registry entry for 24:B6:B8. This is the address the organization registered with the IEEE, which may differ from its current operating address.
