Which company owns MAC address prefix 8C:87:3B?

MAC address prefix 8C:87:3B is registered to Leica Camera AG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 8C:87:3B has a network interface built by Leica Camera AG.

What is the OUI 8C:87:3B?

8C:87:3B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Leica Camera AG. It covers every address from 8C:87:3B:00:00:00 to 8C:87:3B:FF:FF:FF, or 16,777,216 addresses in total. It is also written 8C-87-3B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 8C:87:3B:00:00:00 that is 8C:87:3B — 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 Leica Camera AG located?

Leica Camera AG is listed at Am Leitz-Park 5 Wetzlar Hessen DE 35578 in the IEEE OUI registry entry for 8C:87:3B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
