Which company owns MAC address prefix 48:1C:B9?

MAC address prefix 48:1C:B9 is registered to SZ DJI TECHNOLOGY CO.,LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 48:1C:B9 has a network interface built by SZ DJI TECHNOLOGY CO.,LTD.

What is the OUI 48:1C:B9?

48:1C:B9 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SZ DJI TECHNOLOGY CO.,LTD. It covers every address from 48:1C:B9:00:00:00 to 48:1C:B9:FF:FF:FF, or 16,777,216 addresses in total. It is also written 48-1C-B9.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 48:1C:B9:00:00:00 that is 48:1C:B9 — 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 SZ DJI TECHNOLOGY CO.,LTD located?

SZ DJI TECHNOLOGY CO.,LTD is listed at DJI Sky City, No55 Xianyuan Road, Nanshan District Shenzhen Guangdong CN 518057 in the IEEE OUI registry entry for 48:1C:B9. This is the address the organization registered with the IEEE, which may differ from its current operating address.
