- What is the OUI 38:7A:3C?
- 38:7A:3C 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 38:7A:3C:00:00:00 to 38:7A:3C:FF:FF:FF, or 16,777,216 addresses in total. It is also written 38-7A-3C.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in 38:7A:3C:00:00:00 that is 38:7A:3C — 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.
