Which company owns MAC address prefix 14:DC:E2?

MAC address prefix 14:DC:E2 is registered to THALES AVS France in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 14:DC:E2 has a network interface built by THALES AVS France.

What is the OUI 14:DC:E2?

14:DC:E2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to THALES AVS France. It covers every address from 14:DC:E2:00:00:00 to 14:DC:E2:FF:FF:FF, or 16,777,216 addresses in total. It is also written 14-DC-E2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 14:DC:E2:00:00:00 that is 14:DC:E2 — 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 THALES AVS France located?

THALES AVS France is listed at 75-77 Av. Marcel Dassault Mérignac FR 33700 in the IEEE OUI registry entry for 14:DC:E2. This is the address the organization registered with the IEEE, which may differ from its current operating address.
