What is the OUI BC:67:84?

BC:67:84 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Environics Oy. It covers every address from BC:67:84:00:00:00 to BC:67:84:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-67-84.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:67:84:00:00:00 that is BC:67:84 — 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 Environics Oy located?

Environics Oy is listed at Graanintie 5 Mikkeli FI 50190 in the IEEE OUI registry entry for BC:67:84. This is the address the organization registered with the IEEE, which may differ from its current operating address.
