Which company owns MAC address prefix FC:18:6B?

MAC address prefix FC:18:6B is registered to Dot Origin Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with FC:18:6B has a network interface built by Dot Origin Ltd.

What is the OUI FC:18:6B?

FC:18:6B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Dot Origin Ltd. It covers every address from FC:18:6B:00:00:00 to FC:18:6B:FF:FF:FF, or 16,777,216 addresses in total. It is also written FC-18-6B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in FC:18:6B:00:00:00 that is FC:18:6B — 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 Dot Origin Ltd located?

Dot Origin Ltd is listed at Unit 7 Coopers Place Combe Lane, Wormley Godalming GB GU8 5SZ in the IEEE OUI registry entry for FC:18:6B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
