What is the OUI FC:58:4A?

FC:58:4A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to xiamenshi c-chip technology co., ltd. It covers every address from FC:58:4A:00:00:00 to FC:58:4A:FF:FF:FF, or 16,777,216 addresses in total. It is also written FC-58-4A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in FC:58:4A:00:00:00 that is FC:58:4A — 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 xiamenshi c-chip technology co., ltd located?

xiamenshi c-chip technology co., ltd is listed at Baoyuan Road Shenzhen City Guangdong Province CN 518101 in the IEEE OUI registry entry for FC:58:4A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
