Which company owns MAC address prefix DC:DE:4F?

MAC address prefix DC:DE:4F is registered to Gionee Communication Equipment Co Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:DE:4F has a network interface built by Gionee Communication Equipment Co Ltd.

What is the OUI DC:DE:4F?

DC:DE:4F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Gionee Communication Equipment Co Ltd. It covers every address from DC:DE:4F:00:00:00 to DC:DE:4F:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-DE-4F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:DE:4F:00:00:00 that is DC:DE:4F — 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 Gionee Communication Equipment Co Ltd located?

Gionee Communication Equipment Co Ltd is listed at 21/F Times Technology Building, 7028 Shennan Road Shenzhen Futian District CN 518040 in the IEEE OUI registry entry for DC:DE:4F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
