Which company owns MAC address prefix F0:2F:50?

MAC address prefix F0:2F:50 is registered to Shenzhen SEI Robotics Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F0:2F:50 has a network interface built by Shenzhen SEI Robotics Co.,Ltd.

What is the OUI F0:2F:50?

F0:2F:50 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen SEI Robotics Co.,Ltd. It covers every address from F0:2F:50:00:00:00 to F0:2F:50:FF:FF:FF, or 16,777,216 addresses in total. It is also written F0-2F-50.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F0:2F:50:00:00:00 that is F0:2F:50 — 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 SEI Robotics Co.,Ltd located?

Shenzhen SEI Robotics Co.,Ltd is listed at 11th Floor, Kangtai Group Building, No. 222 Kefa Road, Science and Technology Park Community, Yuehai Street, Nanshan District, Shenzhen Shenzhen Guangdong CN 518000 in the IEEE OUI registry entry for F0:2F:50. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Shenzhen SEI Robotics Co.,Ltd own?

Shenzhen SEI Robotics Co.,Ltd holds 3 OUI prefixes in the IEEE registry, of which F0:2F:50 is one. A device made by Shenzhen SEI Robotics Co.,Ltd could carry a MAC address from any of them.
