What is the OUI 24:90:38?

24:90:38 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Universal Biosensors Pty Ltd. It covers every address from 24:90:38:00:00:00 to 24:90:38:FF:FF:FF, or 16,777,216 addresses in total. It is also written 24-90-38.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 24:90:38:00:00:00 that is 24:90:38 — 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 Universal Biosensors Pty Ltd located?

Universal Biosensors Pty Ltd is listed at 1 Corporate Ave Rowville Victoria AU 3178 in the IEEE OUI registry entry for 24:90:38. This is the address the organization registered with the IEEE, which may differ from its current operating address.
