Which company owns MAC address prefix 64:6B:E7?

MAC address prefix 64:6B:E7 is registered to Qingdao Intelligent&Precise Electronics Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 64:6B:E7 has a network interface built by Qingdao Intelligent&Precise Electronics Co.,Ltd..

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 64:6B:E7:00:00:00 that is 64:6B:E7 — 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.

How many MAC prefixes does Qingdao Intelligent&Precise Electronics Co.,Ltd. own?

Qingdao Intelligent&Precise Electronics Co.,Ltd. holds 22 OUI prefixes in the IEEE registry, of which 64:6B:E7 is one. A device made by Qingdao Intelligent&Precise Electronics Co.,Ltd. could carry a MAC address from any of them.
