Which company owns MAC address prefix 5C:A4:36?

MAC address prefix 5C:A4:36 is registered to Shenzhen G-world Technology Incorporated Company in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 5C:A4:36 has a network interface built by Shenzhen G-world Technology Incorporated Company.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 5C:A4:36:00:00:00 that is 5C:A4:36 — 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.
