FAQ
- Which company owns MAC address prefix AC:4E:65?
- MAC address prefix AC:4E:65 is registered to Fiberhome Telecommunication Technologies Co.,LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with AC:4E:65 has a network interface built by Fiberhome Telecommunication Technologies Co.,LTD.
- What is the OUI AC:4E:65?
- AC:4E:65 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 AC:4E:65:00:00:00 to AC:4E:65:FF:FF:FF, or 16,777,216 addresses in total. It is also written AC-4E-65.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in AC:4E:65:00:00:00 that is AC:4E:65 — 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 AC:4E:65. This is the address the organization registered with the IEEE, which may differ from its current operating address.
- How many MAC prefixes does Fiberhome Telecommunication Technologies Co.,LTD own?
- Fiberhome Telecommunication Technologies Co.,LTD holds 218 OUI prefixes in the IEEE registry, of which AC:4E:65 is one. A device made by Fiberhome Telecommunication Technologies Co.,LTD could carry a MAC address from any of them.
