Which company owns MAC address prefix 0C:BF:74?

MAC address prefix 0C:BF:74 is registered to Morse Micro in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 0C:BF:74 has a network interface built by Morse Micro.

What is the OUI 0C:BF:74?

0C:BF:74 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Morse Micro. It covers every address from 0C:BF:74:00:00:00 to 0C:BF:74:FF:FF:FF, or 16,777,216 addresses in total. It is also written 0C-BF-74.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 0C:BF:74:00:00:00 that is 0C:BF: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 Morse Micro located?

Morse Micro is listed at 113 / 2-4 Cornwallis Street Eveleigh NSW AU 2015 in the IEEE OUI registry entry for 0C:BF:74. This is the address the organization registered with the IEEE, which may differ from its current operating address.
