What is the OUI 64:8D:9E?

64:8D:9E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to IVT Electronic Co.,Ltd. It covers every address from 64:8D:9E:00:00:00 to 64:8D:9E:FF:FF:FF, or 16,777,216 addresses in total. It is also written 64-8D-9E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 64:8D:9E:00:00:00 that is 64:8D:9E — 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 IVT Electronic Co.,Ltd located?

IVT Electronic Co.,Ltd is listed at F building Dongxing Insdustrial Area Dongguan City Guangdong provice CN 523457 in the IEEE OUI registry entry for 64:8D:9E. This is the address the organization registered with the IEEE, which may differ from its current operating address.
