Which company owns MAC address prefix 64:32:A8?

MAC address prefix 64:32:A8 is registered to Intel Corporate in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 64:32:A8 has a network interface built by Intel Corporate.

What is the OUI 64:32:A8?

64:32:A8 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Intel Corporate. It covers every address from 64:32:A8:00:00:00 to 64:32:A8:FF:FF:FF, or 16,777,216 addresses in total. It is also written 64-32-A8.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 64:32:A8:00:00:00 that is 64:32:A8 — 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 Intel Corporate located?

Intel Corporate is listed at Lot 8, Jalan Hi-Tech 2/3 Kulim Kedah MY 09000 in the IEEE OUI registry entry for 64:32:A8. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Intel Corporate own?

Intel Corporate holds 666 OUI prefixes in the IEEE registry, of which 64:32:A8 is one. A device made by Intel Corporate could carry a MAC address from any of them.
