Which company owns MAC address prefix 08:00:06?

MAC address prefix 08:00:06 is registered to SIEMENS AG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:00:06 has a network interface built by SIEMENS AG.

What is the OUI 08:00:06?

08:00:06 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SIEMENS AG. It covers every address from 08:00:06:00:00:00 to 08:00:06:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-00-06.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 08:00:06:00:00:00 that is 08:00:06 — 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 SIEMENS AG located?

SIEMENS AG is listed at Siemens IT Solutions and Services, SIS GO QM O POB 2353 Fuerth DE 90713 in the IEEE OUI registry entry for 08:00:06. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does SIEMENS AG own?

SIEMENS AG holds 7 OUI prefixes in the IEEE registry, of which 08:00:06 is one. A device made by SIEMENS AG could carry a MAC address from any of them.
