Which company owns MAC address prefix F0:73:AE?

MAC address prefix F0:73:AE is registered to PEAK-System Technik in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F0:73:AE has a network interface built by PEAK-System Technik.

What is the OUI F0:73:AE?

F0:73:AE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to PEAK-System Technik. It covers every address from F0:73:AE:00:00:00 to F0:73:AE:FF:FF:FF, or 16,777,216 addresses in total. It is also written F0-73-AE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F0:73:AE:00:00:00 that is F0:73:AE — 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 PEAK-System Technik located?

PEAK-System Technik is listed at Otto-Roehm-Str 69 Darmstadt Hessen DE 64293 in the IEEE OUI registry entry for F0:73:AE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
