Which company owns MAC address prefix A8:40:41?

MAC address prefix A8:40:41 is registered to Dragino Technology Co., Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with A8:40:41 has a network interface built by Dragino Technology Co., Limited.

What is the OUI A8:40:41?

A8:40:41 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Dragino Technology Co., Limited. It covers every address from A8:40:41:00:00:00 to A8:40:41:FF:FF:FF, or 16,777,216 addresses in total. It is also written A8-40-41.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A8:40:41:00:00:00 that is A8:40:41 — 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 Dragino Technology Co., Limited located?

Dragino Technology Co., Limited is listed at 303, Block B, No 8; 349, Jian'An 1 Road,Bao'An Shenzhen GuangDong CN 518101 in the IEEE OUI registry entry for A8:40:41. This is the address the organization registered with the IEEE, which may differ from its current operating address.
