What is the OUI 84:5C:93?

84:5C:93 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Chabrier Services. It covers every address from 84:5C:93:00:00:00 to 84:5C:93:FF:FF:FF, or 16,777,216 addresses in total. It is also written 84-5C-93.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 84:5C:93:00:00:00 that is 84:5C:93 — 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 Chabrier Services located?

Chabrier Services is listed at 354 Chemin de la Pinatte Saint-Peray FR 07130 in the IEEE OUI registry entry for 84:5C:93. This is the address the organization registered with the IEEE, which may differ from its current operating address.
