Which company owns MAC address prefix 24:F5:A2?

MAC address prefix 24:F5:A2 is registered to Belkin International Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 24:F5:A2 has a network interface built by Belkin International Inc..

What is the OUI 24:F5:A2?

24:F5:A2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Belkin International Inc.. It covers every address from 24:F5:A2:00:00:00 to 24:F5:A2:FF:FF:FF, or 16,777,216 addresses in total. It is also written 24-F5-A2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 24:F5:A2:00:00:00 that is 24:F5:A2 — 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 Belkin International Inc. located?

Belkin International Inc. is listed at 12045 East Waterfront Drive Playa Vista null US 90094 in the IEEE OUI registry entry for 24:F5:A2. This is the address the organization registered with the IEEE, which may differ from its current operating address.
