Which company owns MAC address prefix DC:29:19?

MAC address prefix DC:29:19 is registered to AltoBeam(Xiamen)Technology Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:29:19 has a network interface built by AltoBeam(Xiamen)Technology Co., Ltd..

What is the OUI DC:29:19?

DC:29:19 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to AltoBeam(Xiamen)Technology Co., Ltd.. It covers every address from DC:29:19:00:00:00 to DC:29:19:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-29-19.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:29:19:00:00:00 that is DC:29:19 — 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.
