Which company owns MAC address prefix 00:C0:32?

MAC address prefix 00:C0:32 is registered to I-CUBED LIMITED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:C0:32 has a network interface built by I-CUBED LIMITED.

What is the OUI 00:C0:32?

00:C0:32 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to I-CUBED LIMITED. It covers every address from 00:C0:32:00:00:00 to 00:C0:32:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-C0-32.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:C0:32:00:00:00 that is 00:C0:32 — 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 I-CUBED LIMITED located?

I-CUBED LIMITED is listed at UNIT J1, THE POADDOCKS CB1 4DH CB1 4DH GB ENGLAND in the IEEE OUI registry entry for 00:C0:32. This is the address the organization registered with the IEEE, which may differ from its current operating address.
