Which company owns MAC address prefix EC:0E:D6?

MAC address prefix EC:0E:D6 is registered to ITECH INSTRUMENTS SAS in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:0E:D6 has a network interface built by ITECH INSTRUMENTS SAS.

What is the OUI EC:0E:D6?

EC:0E:D6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ITECH INSTRUMENTS SAS. It covers every address from EC:0E:D6:00:00:00 to EC:0E:D6:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-0E-D6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:0E:D6:00:00:00 that is EC:0E:D6 — 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 ITECH INSTRUMENTS SAS located?

ITECH INSTRUMENTS SAS is listed at 3 Avenue de la Maranne Châteauneuf-Les-Martigues FR 13220 in the IEEE OUI registry entry for EC:0E:D6. This is the address the organization registered with the IEEE, which may differ from its current operating address.
