Which company owns MAC address prefix 9C:E1:D6?

MAC address prefix 9C:E1:D6 is registered to Junger Audio-Studiotechnik GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 9C:E1:D6 has a network interface built by Junger Audio-Studiotechnik GmbH.

What is the OUI 9C:E1:D6?

9C:E1:D6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Junger Audio-Studiotechnik GmbH. It covers every address from 9C:E1:D6:00:00:00 to 9C:E1:D6:FF:FF:FF, or 16,777,216 addresses in total. It is also written 9C-E1-D6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 9C:E1:D6:00:00:00 that is 9C:E1:D6 — 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 Junger Audio-Studiotechnik GmbH located?

Junger Audio-Studiotechnik GmbH is listed at Justus-von-Liebig-Strasse 7 12489 Berlin US in the IEEE OUI registry entry for 9C:E1:D6. This is the address the organization registered with the IEEE, which may differ from its current operating address.
