Which company owns MAC address prefix DC:20:08?

MAC address prefix DC:20:08 is registered to ASD Electronics Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:20:08 has a network interface built by ASD Electronics Ltd.

What is the OUI DC:20:08?

DC:20:08 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ASD Electronics Ltd. It covers every address from DC:20:08:00:00:00 to DC:20:08:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-20-08.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:20:08:00:00:00 that is DC:20:08 — 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 ASD Electronics Ltd located?

ASD Electronics Ltd is listed at DEDE INDUSTRIAL PARK,JIAN'AN ROAD,HIGH-TECH Shenzhen Guang Dong CN 518103 in the IEEE OUI registry entry for DC:20:08. This is the address the organization registered with the IEEE, which may differ from its current operating address.
