Which company owns MAC address prefix 54:F8:76?

MAC address prefix 54:F8:76 is registered to ABB AG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 54:F8:76 has a network interface built by ABB AG.

What is the OUI 54:F8:76?

54:F8:76 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ABB AG. It covers every address from 54:F8:76:00:00:00 to 54:F8:76:FF:FF:FF, or 16,777,216 addresses in total. It is also written 54-F8-76.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 54:F8:76:00:00:00 that is 54:F8:76 — 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 ABB AG located?

ABB AG is listed at Trafoweg 4 Halle / Saale Saxony-Anhalt DE 06112 in the IEEE OUI registry entry for 54:F8:76. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does ABB AG own?

ABB AG holds 2 OUI prefixes in the IEEE registry, of which 54:F8:76 is one. A device made by ABB AG could carry a MAC address from any of them.
