Which company owns MAC address prefix 10:83:D2?

MAC address prefix 10:83:D2 is registered to Microseven Systems, LLC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 10:83:D2 has a network interface built by Microseven Systems, LLC.

What is the OUI 10:83:D2?

10:83:D2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Microseven Systems, LLC. It covers every address from 10:83:D2:00:00:00 to 10:83:D2:FF:FF:FF, or 16,777,216 addresses in total. It is also written 10-83-D2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:83:D2:00:00:00 that is 10:83:D2 — 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 Microseven Systems, LLC located?

Microseven Systems, LLC is listed at 404 South Lemon Ave., #9 Walnut California US 91789 in the IEEE OUI registry entry for 10:83:D2. This is the address the organization registered with the IEEE, which may differ from its current operating address.
