Which company owns MAC address prefix 9C:18:74?

MAC address prefix 9C:18:74 is registered to Nokia Danmark A/S in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 9C:18:74 has a network interface built by Nokia Danmark A/S.

What is the OUI 9C:18:74?

9C:18:74 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Nokia Danmark A/S. It covers every address from 9C:18:74:00:00:00 to 9C:18:74:FF:FF:FF, or 16,777,216 addresses in total. It is also written 9C-18-74.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 9C:18:74:00:00:00 that is 9C:18:74 — 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 Danmark A/S located?

Nokia Danmark A/S is listed at Frederikskaj Copenhagen V DK DK-1790V in the IEEE OUI registry entry for 9C:18:74. This is the address the organization registered with the IEEE, which may differ from its current operating address.

Nokia Danmark A/S holds 72 OUI prefixes in the IEEE registry, of which 9C:18:74 is one. A device made by Nokia Danmark A/S could carry a MAC address from any of them.
