Which company owns MAC address prefix 84:C7:E2?

MAC address prefix 84:C7:E2 is registered to VusionGroup in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 84:C7:E2 has a network interface built by VusionGroup.

What is the OUI 84:C7:E2?

84:C7:E2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to VusionGroup. It covers every address from 84:C7:E2:00:00:00 to 84:C7:E2:FF:FF:FF, or 16,777,216 addresses in total. It is also written 84-C7-E2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 84:C7:E2:00:00:00 that is 84:C7:E2 — 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 VusionGroup located?

VusionGroup is listed at Kalsdorfer Straße 12 Fernitz-Mellach Steiermark AT 8072 in the IEEE OUI registry entry for 84:C7:E2. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does VusionGroup own?

VusionGroup holds 15 OUI prefixes in the IEEE registry, of which 84:C7:E2 is one. A device made by VusionGroup could carry a MAC address from any of them.
