Which company owns MAC address prefix 08:0C:0B?

MAC address prefix 08:0C:0B is registered to SysMik GmbH Dresden in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:0C:0B has a network interface built by SysMik GmbH Dresden.

What is the OUI 08:0C:0B?

08:0C:0B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SysMik GmbH Dresden. It covers every address from 08:0C:0B:00:00:00 to 08:0C:0B:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-0C-0B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 08:0C:0B:00:00:00 that is 08:0C:0B — 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 SysMik GmbH Dresden located?

SysMik GmbH Dresden is listed at Bertolt-Brecht-Allee 24 Dresden DE 01309 in the IEEE OUI registry entry for 08:0C:0B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
