Which company owns MAC address prefix 54:D1:B0?

MAC address prefix 54:D1:B0 is registered to Universal Laser Systems, Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 54:D1:B0 has a network interface built by Universal Laser Systems, Inc.

What is the OUI 54:D1:B0?

54:D1:B0 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Universal Laser Systems, Inc. It covers every address from 54:D1:B0:00:00:00 to 54:D1:B0:FF:FF:FF, or 16,777,216 addresses in total. It is also written 54-D1-B0.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 54:D1:B0:00:00:00 that is 54:D1:B0 — 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 Laser Systems, Inc located?

Universal Laser Systems, Inc is listed at 16008 N 81st street scottsdale az US 85260 in the IEEE OUI registry entry for 54:D1:B0. This is the address the organization registered with the IEEE, which may differ from its current operating address.
