Which company owns MAC address prefix 58:53:C0?

MAC address prefix 58:53:C0 is registered to Beijing Guang Runtong Technology Development Company co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 58:53:C0 has a network interface built by Beijing Guang Runtong Technology Development Company co.,Ltd.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 58:53:C0:00:00:00 that is 58:53:C0 — 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.
