Which company owns MAC address prefix 84:EB:3F?

MAC address prefix 84:EB:3F is registered to Vivint Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 84:EB:3F has a network interface built by Vivint Inc.

What is the OUI 84:EB:3F?

84:EB:3F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Vivint Inc. It covers every address from 84:EB:3F:00:00:00 to 84:EB:3F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 84-EB-3F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 84:EB:3F:00:00:00 that is 84:EB:3F — 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 Vivint Inc located?

Vivint Inc is listed at 3401 N Ashton Blvd Lehi UT US 84043 in the IEEE OUI registry entry for 84:EB:3F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
