FAQ
- Which company owns MAC address prefix B8:DF:D4?
- MAC address prefix B8:DF:D4 is registered to Fiberhome Telecommunication Technologies Co.,LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B8:DF:D4 has a network interface built by Fiberhome Telecommunication Technologies Co.,LTD.
- What is the OUI B8:DF:D4?
- B8:DF:D4 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 B8:DF:D4:00:00:00 to B8:DF:D4:FF:FF:FF, or 16,777,216 addresses in total. It is also written B8-DF-D4.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in B8:DF:D4:00:00:00 that is B8:DF:D4 — 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 Fiberhome Telecommunication Technologies Co.,LTD located?
- Fiberhome Telecommunication Technologies Co.,LTD is listed at No.5 DongXin Road Wuhan Hubei CN 430074 in the IEEE OUI registry entry for B8:DF:D4. This is the address the organization registered with the IEEE, which may differ from its current operating address.
