Which company owns MAC address prefix DC:1A:01?

MAC address prefix DC:1A:01 is registered to Ecoliv Technology ( Shenzhen ) Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:1A:01 has a network interface built by Ecoliv Technology ( Shenzhen ) Ltd..

What is the OUI DC:1A:01?

DC:1A:01 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ecoliv Technology ( Shenzhen ) Ltd.. It covers every address from DC:1A:01:00:00:00 to DC:1A:01:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-1A-01.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:1A:01:00:00:00 that is DC:1A:01 — 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.
