Which company owns MAC address prefix E0:B7:2E?

MAC address prefix E0:B7:2E is registered to ShenZhen Qualmesh Technology Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:B7:2E has a network interface built by ShenZhen Qualmesh Technology Co.,Ltd..

What is the OUI E0:B7:2E?

E0:B7:2E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ShenZhen Qualmesh Technology Co.,Ltd.. It covers every address from E0:B7:2E:00:00:00 to E0:B7:2E:FF:FF:FF, or 16,777,216 addresses in total. It is also written E0-B7-2E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:B7:2E:00:00:00 that is E0:B7:2E — 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.
