Which company owns MAC address prefix CC:9E:CA?

MAC address prefix CC:9E:CA is registered to HMD Global Oy in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:9E:CA has a network interface built by HMD Global Oy.

What is the OUI CC:9E:CA?

CC:9E:CA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to HMD Global Oy. It covers every address from CC:9E:CA:00:00:00 to CC:9E:CA:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-9E-CA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:9E:CA:00:00:00 that is CC:9E:CA — 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 HMD Global Oy located?

HMD Global Oy is listed at Bertel Jungin aukio 9 Espoo Espoo FI 02600 in the IEEE OUI registry entry for CC:9E:CA. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does HMD Global Oy own?
