FAQ
- Which company owns MAC address prefix C8:58:6A?
- MAC address prefix C8:58:6A is registered to Beijing Winner Microelectronics Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C8:58:6A has a network interface built by Beijing Winner Microelectronics Co.,Ltd..
- What is the OUI C8:58:6A?
- C8:58:6A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Beijing Winner Microelectronics Co.,Ltd.. It covers every address from C8:58:6A:00:00:00 to C8:58:6A:FF:FF:FF, or 16,777,216 addresses in total. It is also written C8-58-6A.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in C8:58:6A:00:00:00 that is C8:58:6A — 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.
