What is the OUI E0:79:5E?

E0:79:5E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Wuxi Xiaohu Technology Co.,Ltd.. It covers every address from E0:79:5E:00:00:00 to E0:79:5E:FF:FF:FF, or 16,777,216 addresses in total. It is also written E0-79-5E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:79:5E:00:00:00 that is E0:79:5E — 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 Wuxi Xiaohu Technology Co.,Ltd. located?
