What is the OUI 7C:0C:F6?

7C:0C:F6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Guangdong Huiwei High-tech Co., Ltd.. It covers every address from 7C:0C:F6:00:00:00 to 7C:0C:F6:FF:FF:FF, or 16,777,216 addresses in total. It is also written 7C-0C-F6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 7C:0C:F6:00:00:00 that is 7C:0C:F6 — 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 Guangdong Huiwei High-tech Co., Ltd. located?
