Which company owns MAC address prefix CC:58:C7?

MAC address prefix CC:58:C7 is registered to Nokia in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:58:C7 has a network interface built by Nokia.

What is the OUI CC:58:C7?

CC:58:C7 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Nokia. It covers every address from CC:58:C7:00:00:00 to CC:58:C7:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-58-C7.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:58:C7:00:00:00 that is CC:58:C7 — 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 Nokia located?

Nokia is listed at 600 March Road Kanata Ontario CA K2K 2E6 in the IEEE OUI registry entry for CC:58:C7. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Nokia own?

Nokia holds 156 OUI prefixes in the IEEE registry, of which CC:58:C7 is one. A device made by Nokia could carry a MAC address from any of them.
