Which company owns MAC address prefix 4C:D7:C8?

MAC address prefix 4C:D7:C8 is registered to Guangzhou V-Solution Telecommunication Technology Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 4C:D7:C8 has a network interface built by Guangzhou V-Solution Telecommunication Technology Co.,Ltd..

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 4C:D7:C8:00:00:00 that is 4C:D7:C8 — 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.

How many MAC prefixes does Guangzhou V-Solution Telecommunication Technology Co.,Ltd. own?

Guangzhou V-Solution Telecommunication Technology Co.,Ltd. holds 7 OUI prefixes in the IEEE registry, of which 4C:D7:C8 is one. A device made by Guangzhou V-Solution Telecommunication Technology Co.,Ltd. could carry a MAC address from any of them.
