Which company owns MAC address prefix 0C:5F:35?

MAC address prefix 0C:5F:35 is registered to Niagara Video Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 0C:5F:35 has a network interface built by Niagara Video Corporation.

What is the OUI 0C:5F:35?

0C:5F:35 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Niagara Video Corporation. It covers every address from 0C:5F:35:00:00:00 to 0C:5F:35:FF:FF:FF, or 16,777,216 addresses in total. It is also written 0C-5F-35.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 0C:5F:35:00:00:00 that is 0C:5F:35 — 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 Niagara Video Corporation located?

Niagara Video Corporation is listed at 5627 Stoneridge Drive, Suite 316 Pleasanton CA US 94588 in the IEEE OUI registry entry for 0C:5F:35. This is the address the organization registered with the IEEE, which may differ from its current operating address.
