Which company owns MAC address prefix 3C:F7:48?

MAC address prefix 3C:F7:48 is registered to Shenzhen Linsn Technology Development Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 3C:F7:48 has a network interface built by Shenzhen Linsn Technology Development Co.,Ltd.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 3C:F7:48:00:00:00 that is 3C:F7:48 — 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 Shenzhen Linsn Technology Development Co.,Ltd located?

Shenzhen Linsn Technology Development Co.,Ltd is listed at Floor 4,Block 7,Zone 2,Baiwangxin Industrial Park Shenzhen Guangdong CN 518055 in the IEEE OUI registry entry for 3C:F7:48. This is the address the organization registered with the IEEE, which may differ from its current operating address.
