Which company owns MAC address prefix 38:B5:BD?

MAC address prefix 38:B5:BD is registered to E.G.O. Elektro-Ger in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 38:B5:BD has a network interface built by E.G.O. Elektro-Ger.

What is the OUI 38:B5:BD?

38:B5:BD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to E.G.O. Elektro-Ger. It covers every address from 38:B5:BD:00:00:00 to 38:B5:BD:FF:FF:FF, or 16,777,216 addresses in total. It is also written 38-B5-BD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 38:B5:BD:00:00:00 that is 38:B5:BD — 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 E.G.O. Elektro-Ger located?

E.G.O. Elektro-Ger is listed at Einkauf Oberderdingen DE 75038 in the IEEE OUI registry entry for 38:B5:BD. This is the address the organization registered with the IEEE, which may differ from its current operating address.
