Which company owns MAC address prefix FC:50:0C?

What is the OUI FC:50:0C?

FC:50:0C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Sitehop Ltd. It covers every address from FC:50:0C:00:00:00 to FC:50:0C:FF:FF:FF, or 16,777,216 addresses in total. It is also written FC-50-0C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in FC:50:0C:00:00:00 that is FC:50:0C — 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 Sitehop Ltd located?

Sitehop Ltd is listed at 9 South Street Sheffield South Yorkshire GB S2 5QX in the IEEE OUI registry entry for FC:50:0C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
