Which company owns MAC address prefix BC:22:28?

MAC address prefix BC:22:28 is registered to D-Link International in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:22:28 has a network interface built by D-Link International.

What is the OUI BC:22:28?

BC:22:28 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to D-Link International. It covers every address from BC:22:28:00:00:00 to BC:22:28:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-22-28.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:22:28:00:00:00 that is BC:22:28 — 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 D-Link International located?

D-Link International is listed at 1 Internal Business Park, #03-12,The Synergy Singapore Singapore SG 609917 in the IEEE OUI registry entry for BC:22:28. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does D-Link International own?

D-Link International holds 60 OUI prefixes in the IEEE registry, of which BC:22:28 is one. A device made by D-Link International could carry a MAC address from any of them.
