Which company owns MAC address prefix 78:EC:74?

MAC address prefix 78:EC:74 is registered to Kyland-USA in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 78:EC:74 has a network interface built by Kyland-USA.

What is the OUI 78:EC:74?

78:EC:74 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Kyland-USA. It covers every address from 78:EC:74:00:00:00 to 78:EC:74:FF:FF:FF, or 16,777,216 addresses in total. It is also written 78-EC-74.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 78:EC:74:00:00:00 that is 78:EC: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 Kyland-USA located?

Kyland-USA is listed at 1107 SE Willow Pl Blue Springs MO US 64014 in the IEEE OUI registry entry for 78:EC:74. This is the address the organization registered with the IEEE, which may differ from its current operating address.
