Which company owns MAC address prefix DC:A6:32?

MAC address prefix DC:A6:32 is registered to Raspberry Pi Trading Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:A6:32 has a network interface built by Raspberry Pi Trading Ltd.

What is the OUI DC:A6:32?

DC:A6:32 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Raspberry Pi Trading Ltd. It covers every address from DC:A6:32:00:00:00 to DC:A6:32:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-A6-32.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:A6:32:00:00:00 that is DC:A6:32 — 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 Raspberry Pi Trading Ltd located?

Raspberry Pi Trading Ltd is listed at Maurice Wilkes Building, Cowley Road Cambridge GB CB4 0DS in the IEEE OUI registry entry for DC:A6:32. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Raspberry Pi Trading Ltd own?

Raspberry Pi Trading Ltd holds 4 OUI prefixes in the IEEE registry, of which DC:A6:32 is one. A device made by Raspberry Pi Trading Ltd could carry a MAC address from any of them.
