Which company owns MAC address prefix E4:67:A6?

MAC address prefix E4:67:A6 is registered to BSH Hausgeräte GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E4:67:A6 has a network interface built by BSH Hausgeräte GmbH.

What is the OUI E4:67:A6?

E4:67:A6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to BSH Hausgeräte GmbH. It covers every address from E4:67:A6:00:00:00 to E4:67:A6:FF:FF:FF, or 16,777,216 addresses in total. It is also written E4-67-A6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E4:67:A6:00:00:00 that is E4:67:A6 — 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 BSH Hausgeräte GmbH located?

BSH Hausgeräte GmbH is listed at Im Gewerbepark B35 Regensburg Bayern DE 93059 in the IEEE OUI registry entry for E4:67:A6. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does BSH Hausgeräte GmbH own?

BSH Hausgeräte GmbH holds 7 OUI prefixes in the IEEE registry, of which E4:67:A6 is one. A device made by BSH Hausgeräte GmbH could carry a MAC address from any of them.
