What is the OUI 54:A3:FA?

54:A3:FA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to BQT Solutions (Australia)Pty Ltd. It covers every address from 54:A3:FA:00:00:00 to 54:A3:FA:FF:FF:FF, or 16,777,216 addresses in total. It is also written 54-A3-FA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 54:A3:FA:00:00:00 that is 54:A3:FA — 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 BQT Solutions (Australia)Pty Ltd located?

BQT Solutions (Australia)Pty Ltd is listed at Unit 29, 1 Talavera Road North Ryde NSW AU 2113 in the IEEE OUI registry entry for 54:A3:FA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
