Which company owns MAC address prefix 14:AE:68?

MAC address prefix 14:AE:68 is registered to KLG Smartec in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 14:AE:68 has a network interface built by KLG Smartec.

What is the OUI 14:AE:68?

14:AE:68 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to KLG Smartec. It covers every address from 14:AE:68:00:00:00 to 14:AE:68:FF:FF:FF, or 16,777,216 addresses in total. It is also written 14-AE-68.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 14:AE:68:00:00:00 that is 14:AE:68 — 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 KLG Smartec located?

KLG Smartec is listed at Arbachtalstrasse 6, 72800 Eningen DE 72800 in the IEEE OUI registry entry for 14:AE:68. This is the address the organization registered with the IEEE, which may differ from its current operating address.
