Which company owns MAC address prefix 14:5A:83?

MAC address prefix 14:5A:83 is registered to Logi-D inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 14:5A:83 has a network interface built by Logi-D inc.

What is the OUI 14:5A:83?

14:5A:83 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Logi-D inc. It covers every address from 14:5A:83:00:00:00 to 14:5A:83:FF:FF:FF, or 16,777,216 addresses in total. It is also written 14-5A-83.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 14:5A:83:00:00:00 that is 14:5A:83 — 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 Logi-D inc located?

Logi-D inc is listed at 5550 Des Rossignol Blvd Laval Quebec CA H7L 5W6 in the IEEE OUI registry entry for 14:5A:83. This is the address the organization registered with the IEEE, which may differ from its current operating address.
