Which company owns MAC address prefix E8:6C:DA?

MAC address prefix E8:6C:DA is registered to Supercomputers and Neurocomputers Research Center in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E8:6C:DA has a network interface built by Supercomputers and Neurocomputers Research Center.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E8:6C:DA:00:00:00 that is E8:6C:DA — 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.
