Which company owns MAC address prefix BC:AD:90?

MAC address prefix BC:AD:90 is registered to Kymeta Purchasing in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:AD:90 has a network interface built by Kymeta Purchasing.

What is the OUI BC:AD:90?

BC:AD:90 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Kymeta Purchasing. It covers every address from BC:AD:90:00:00:00 to BC:AD:90:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-AD-90.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:AD:90:00:00:00 that is BC:AD:90 — 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 Kymeta Purchasing located?

Kymeta Purchasing is listed at 12034 134th Ct NE #105 Redmond WA US 98052 in the IEEE OUI registry entry for BC:AD:90. This is the address the organization registered with the IEEE, which may differ from its current operating address.
