Which company owns MAC address prefix 10:28:34?

MAC address prefix 10:28:34 is registered to SALZ Automation GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 10:28:34 has a network interface built by SALZ Automation GmbH.

What is the OUI 10:28:34?

10:28:34 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SALZ Automation GmbH. It covers every address from 10:28:34:00:00:00 to 10:28:34:FF:FF:FF, or 16,777,216 addresses in total. It is also written 10-28-34.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:28:34:00:00:00 that is 10:28:34 — 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 SALZ Automation GmbH located?

SALZ Automation GmbH is listed at Max-Planck-Strasse 64 Bald Salzuflen DE 32107 in the IEEE OUI registry entry for 10:28:34. This is the address the organization registered with the IEEE, which may differ from its current operating address.
