Which company owns MAC address prefix 80:0B:51?

MAC address prefix 80:0B:51 is registered to Chengdu XGimi Technology Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 80:0B:51 has a network interface built by Chengdu XGimi Technology Co.,Ltd.

What is the OUI 80:0B:51?

80:0B:51 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Chengdu XGimi Technology Co.,Ltd. It covers every address from 80:0B:51:00:00:00 to 80:0B:51:FF:FF:FF, or 16,777,216 addresses in total. It is also written 80-0B-51.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 80:0B:51:00:00:00 that is 80:0B:51 — 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 Chengdu XGimi Technology Co.,Ltd located?

Chengdu XGimi Technology Co.,Ltd is listed at 5F Building A7,Tianfu Software Park,Tianfu Chengdu Sichuan CN 610041 in the IEEE OUI registry entry for 80:0B:51. This is the address the organization registered with the IEEE, which may differ from its current operating address.
