Which company owns MAC address prefix 00:D0:1F?

What is the OUI 00:D0:1F?

00:D0:1F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Senetas Corporation Ltd. It covers every address from 00:D0:1F:00:00:00 to 00:D0:1F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-D0-1F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:D0:1F:00:00:00 that is 00:D0:1F — 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 Senetas Corporation Ltd located?

Senetas Corporation Ltd is listed at 1/11 Queens Road consolidation AU consolidation in the IEEE OUI registry entry for 00:D0:1F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
