What is the OUI C8:D4:29?

C8:D4:29 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Muehlbauer AG. It covers every address from C8:D4:29:00:00:00 to C8:D4:29:FF:FF:FF, or 16,777,216 addresses in total. It is also written C8-D4-29.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C8:D4:29:00:00:00 that is C8:D4:29 — 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 Muehlbauer AG located?

Muehlbauer AG is listed at Josef-Mühlbauer-Platz 1 Roding Bavaria DE 93426 in the IEEE OUI registry entry for C8:D4:29. This is the address the organization registered with the IEEE, which may differ from its current operating address.
