Which company owns MAC address prefix 10:2C:B1?

MAC address prefix 10:2C:B1 is registered to Smart Innovation LLC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 10:2C:B1 has a network interface built by Smart Innovation LLC.

What is the OUI 10:2C:B1?

10:2C:B1 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Smart Innovation LLC. It covers every address from 10:2C:B1:00:00:00 to 10:2C:B1:FF:FF:FF, or 16,777,216 addresses in total. It is also written 10-2C-B1.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:2C:B1:00:00:00 that is 10:2C:B1 — 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 Smart Innovation LLC located?

Smart Innovation LLC is listed at 400 108th Ave NE?Ste 400 Bellevue WA US 98004 in the IEEE OUI registry entry for 10:2C:B1. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Smart Innovation LLC own?

Smart Innovation LLC holds 5 OUI prefixes in the IEEE registry, of which 10:2C:B1 is one. A device made by Smart Innovation LLC could carry a MAC address from any of them.
