What is the OUI 24:08:5D?

24:08:5D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to AUMOVIO Aftermarket GmbH. It covers every address from 24:08:5D:00:00:00 to 24:08:5D:FF:FF:FF, or 16,777,216 addresses in total. It is also written 24-08-5D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 24:08:5D:00:00:00 that is 24:08:5D — 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 AUMOVIO Aftermarket GmbH located?

AUMOVIO Aftermarket GmbH is listed at Sodener Strasse 9 Schwalbach am Taunus Hessen DE 65824 in the IEEE OUI registry entry for 24:08:5D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
