Which company owns MAC address prefix 18:90:24?

MAC address prefix 18:90:24 is registered to Astera LED Technology GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 18:90:24 has a network interface built by Astera LED Technology GmbH.

What is the OUI 18:90:24?

18:90:24 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Astera LED Technology GmbH. It covers every address from 18:90:24:00:00:00 to 18:90:24:FF:FF:FF, or 16,777,216 addresses in total. It is also written 18-90-24.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 18:90:24:00:00:00 that is 18:90:24 — 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 Astera LED Technology GmbH located?

Astera LED Technology GmbH is listed at Schatzbogen 60 Munich Bayern DE 81829 in the IEEE OUI registry entry for 18:90:24. This is the address the organization registered with the IEEE, which may differ from its current operating address.
