What is the OUI A4:56:02?

A4:56:02 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to fenglian Technology Co.,Ltd.. It covers every address from A4:56:02:00:00:00 to A4:56:02:FF:FF:FF, or 16,777,216 addresses in total. It is also written A4-56-02.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A4:56:02:00:00:00 that is A4:56:02 — 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 fenglian Technology Co.,Ltd. located?
