Which company owns MAC address prefix 5C:2F:AF?

MAC address prefix 5C:2F:AF is registered to HomeWizard B.V. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 5C:2F:AF has a network interface built by HomeWizard B.V..

What is the OUI 5C:2F:AF?

5C:2F:AF is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to HomeWizard B.V.. It covers every address from 5C:2F:AF:00:00:00 to 5C:2F:AF:FF:FF:FF, or 16,777,216 addresses in total. It is also written 5C-2F-AF.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 5C:2F:AF:00:00:00 that is 5C:2F:AF — 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 HomeWizard B.V. located?

HomeWizard B.V. is listed at Keyserswey 79 Noordwijk Zuid-Holland NL 2201CX in the IEEE OUI registry entry for 5C:2F:AF. This is the address the organization registered with the IEEE, which may differ from its current operating address.
