Which company owns MAC address prefix 84:E6:29?

MAC address prefix 84:E6:29 is registered to Bluwan SA in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 84:E6:29 has a network interface built by Bluwan SA.

What is the OUI 84:E6:29?

84:E6:29 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Bluwan SA. It covers every address from 84:E6:29:00:00:00 to 84:E6:29:FF:FF:FF, or 16,777,216 addresses in total. It is also written 84-E6-29.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 84:E6:29:00:00:00 that is 84:E6:29 — 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 Bluwan SA located?

Bluwan SA is listed at Espace Lumiere, Bat 2 Chatou FR 78400 in the IEEE OUI registry entry for 84:E6:29. This is the address the organization registered with the IEEE, which may differ from its current operating address.
