Which company owns MAC address prefix 64:25:EC?

MAC address prefix 64:25:EC is registered to guangdong kesheng zhixun technology in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 64:25:EC has a network interface built by guangdong kesheng zhixun technology.

What is the OUI 64:25:EC?

64:25:EC is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to guangdong kesheng zhixun technology. It covers every address from 64:25:EC:00:00:00 to 64:25:EC:FF:FF:FF, or 16,777,216 addresses in total. It is also written 64-25-EC.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 64:25:EC:00:00:00 that is 64:25:EC — 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.
