Which company owns MAC address prefix E0:6C:A6?

MAC address prefix E0:6C:A6 is registered to Creotech Quantum SA in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:6C:A6 has a network interface built by Creotech Quantum SA.

What is the OUI E0:6C:A6?

E0:6C:A6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Creotech Quantum SA. It covers every address from E0:6C:A6:00:00:00 to E0:6C:A6:FF:FF:FF, or 16,777,216 addresses in total. It is also written E0-6C-A6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:6C:A6:00:00:00 that is E0:6C:A6 — 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 Creotech Quantum SA located?

Creotech Quantum SA is listed at Migdalowa 4 Warsaw Mazovia PL 02-796 in the IEEE OUI registry entry for E0:6C:A6. This is the address the organization registered with the IEEE, which may differ from its current operating address.
