Which company owns MAC address prefix 4C:EB:76?

MAC address prefix 4C:EB:76 is registered to Murrelektronik GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 4C:EB:76 has a network interface built by Murrelektronik GmbH.

What is the OUI 4C:EB:76?

4C:EB:76 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Murrelektronik GmbH. It covers every address from 4C:EB:76:00:00:00 to 4C:EB:76:FF:FF:FF, or 16,777,216 addresses in total. It is also written 4C-EB-76.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 4C:EB:76:00:00:00 that is 4C:EB:76 — 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 Murrelektronik GmbH located?

Murrelektronik GmbH is listed at Falkenstraße 3 Oppenweiler Baden-Württemberg DE 71570 in the IEEE OUI registry entry for 4C:EB:76. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Murrelektronik GmbH own?

Murrelektronik GmbH holds 2 OUI prefixes in the IEEE registry, of which 4C:EB:76 is one. A device made by Murrelektronik GmbH could carry a MAC address from any of them.
