What is the OUI 54:FD:BF?

54:FD:BF is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Scheidt & Bachmann GmbH. It covers every address from 54:FD:BF:00:00:00 to 54:FD:BF:FF:FF:FF, or 16,777,216 addresses in total. It is also written 54-FD-BF.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 54:FD:BF:00:00:00 that is 54:FD:BF — 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 Scheidt & Bachmann GmbH located?

Scheidt & Bachmann GmbH is listed at Breite Strasse 132 Moenchengladbach NRW DE 41238 in the IEEE OUI registry entry for 54:FD:BF. This is the address the organization registered with the IEEE, which may differ from its current operating address.
