Which company owns MAC address prefix E4:1A:1D?

MAC address prefix E4:1A:1D is registered to NOVEA ENERGIES in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E4:1A:1D has a network interface built by NOVEA ENERGIES.

What is the OUI E4:1A:1D?

E4:1A:1D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to NOVEA ENERGIES. It covers every address from E4:1A:1D:00:00:00 to E4:1A:1D:FF:FF:FF, or 16,777,216 addresses in total. It is also written E4-1A-1D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E4:1A:1D:00:00:00 that is E4:1A:1D — 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 NOVEA ENERGIES located?

NOVEA ENERGIES is listed at 3 rue Joseph Fourier BEAUCOUZE Pays de la Loire FR 49070 in the IEEE OUI registry entry for E4:1A:1D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
