Which company owns MAC address prefix FC:5B:24?

MAC address prefix FC:5B:24 is registered to Weibel Scientific A/S in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with FC:5B:24 has a network interface built by Weibel Scientific A/S.

What is the OUI FC:5B:24?

FC:5B:24 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Weibel Scientific A/S. It covers every address from FC:5B:24:00:00:00 to FC:5B:24:FF:FF:FF, or 16,777,216 addresses in total. It is also written FC-5B-24.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in FC:5B:24:00:00:00 that is FC:5B:24 — 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 Weibel Scientific A/S located?

Weibel Scientific A/S is listed at Solvang 30 Alleroed DK 3450 in the IEEE OUI registry entry for FC:5B:24. This is the address the organization registered with the IEEE, which may differ from its current operating address.
