Which company owns MAC address prefix 0C:84:84?

MAC address prefix 0C:84:84 is registered to Zenovia Electronics Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 0C:84:84 has a network interface built by Zenovia Electronics Inc..

What is the OUI 0C:84:84?

0C:84:84 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Zenovia Electronics Inc.. It covers every address from 0C:84:84:00:00:00 to 0C:84:84:FF:FF:FF, or 16,777,216 addresses in total. It is also written 0C-84-84.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 0C:84:84:00:00:00 that is 0C:84:84 — 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 Zenovia Electronics Inc. located?

Zenovia Electronics Inc. is listed at #206, 506B St. Albert Rd. St. Albert AB CA T8N 5Z1 in the IEEE OUI registry entry for 0C:84:84. This is the address the organization registered with the IEEE, which may differ from its current operating address.
