Which company owns MAC address prefix D8:FF:C3?

MAC address prefix D8:FF:C3 is registered to Shenzhen 3SNIC information technology company Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D8:FF:C3 has a network interface built by Shenzhen 3SNIC information technology company Limited.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D8:FF:C3:00:00:00 that is D8:FF:C3 — 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.
