Which company owns MAC address prefix 4C:14:80?

MAC address prefix 4C:14:80 is registered to NOREGON SYSTEMS, INC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 4C:14:80 has a network interface built by NOREGON SYSTEMS, INC.

What is the OUI 4C:14:80?

4C:14:80 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to NOREGON SYSTEMS, INC. It covers every address from 4C:14:80:00:00:00 to 4C:14:80:FF:FF:FF, or 16,777,216 addresses in total. It is also written 4C-14-80.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 4C:14:80:00:00:00 that is 4C:14:80 — 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 NOREGON SYSTEMS, INC located?

NOREGON SYSTEMS, INC is listed at 100 N. MAIN ST. SUITE 2200 WINSTON - SALEM NC US 27101 in the IEEE OUI registry entry for 4C:14:80. This is the address the organization registered with the IEEE, which may differ from its current operating address.
