Which company owns MAC address prefix 5C:07:6F?

MAC address prefix 5C:07:6F is registered to Thought Creator in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 5C:07:6F has a network interface built by Thought Creator.

What is the OUI 5C:07:6F?

5C:07:6F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Thought Creator. It covers every address from 5C:07:6F:00:00:00 to 5C:07:6F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 5C-07-6F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 5C:07:6F:00:00:00 that is 5C:07:6F — 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 Thought Creator located?

Thought Creator is listed at Largo da Pirâmide, Nº 3, Sala D Oeiras Lisboa PT 2795-156 Linda-a-Velha in the IEEE OUI registry entry for 5C:07:6F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
