Which company owns MAC address prefix 38:17:30?

MAC address prefix 38:17:30 is registered to Ulrich Lippert GmbH & Co KG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 38:17:30 has a network interface built by Ulrich Lippert GmbH & Co KG.

What is the OUI 38:17:30?

38:17:30 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ulrich Lippert GmbH & Co KG. It covers every address from 38:17:30:00:00:00 to 38:17:30:FF:FF:FF, or 16,777,216 addresses in total. It is also written 38-17-30.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 38:17:30:00:00:00 that is 38:17:30 — 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 Ulrich Lippert GmbH & Co KG located?

Ulrich Lippert GmbH & Co KG is listed at Christian-Henkel-Str. 12 Berlin DE 12349 in the IEEE OUI registry entry for 38:17:30. This is the address the organization registered with the IEEE, which may differ from its current operating address.
