FAQ
- Which company owns MAC address prefix A0:13:CB?
- MAC address prefix A0:13:CB is registered to Fiberhome Telecommunication Technologies Co.,LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with A0:13:CB has a network interface built by Fiberhome Telecommunication Technologies Co.,LTD.
- What is the OUI A0:13:CB?
- A0:13:CB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Fiberhome Telecommunication Technologies Co.,LTD. It covers every address from A0:13:CB:00:00:00 to A0:13:CB:FF:FF:FF, or 16,777,216 addresses in total. It is also written A0-13-CB.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in A0:13:CB:00:00:00 that is A0:13:CB — 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.
