Which company owns MAC address prefix 58:C2:32?

MAC address prefix 58:C2:32 is registered to NEC Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 58:C2:32 has a network interface built by NEC Corporation.

What is the OUI 58:C2:32?

58:C2:32 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to NEC Corporation. It covers every address from 58:C2:32:00:00:00 to 58:C2:32:FF:FF:FF, or 16,777,216 addresses in total. It is also written 58-C2-32.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 58:C2:32:00:00:00 that is 58:C2:32 — 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 NEC Corporation located?

NEC Corporation is listed at 1753, Shimonumabe, Nakahara-Ku, Kawasaki Kanagawa JP 211-8666 in the IEEE OUI registry entry for 58:C2:32. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does NEC Corporation own?

NEC Corporation holds 9 OUI prefixes in the IEEE registry, of which 58:C2:32 is one. A device made by NEC Corporation could carry a MAC address from any of them.
