Which company owns MAC address prefix EC:F6:BD?

MAC address prefix EC:F6:BD is registered to SNCF MOBILITÉS in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:F6:BD has a network interface built by SNCF MOBILITÉS.

What is the OUI EC:F6:BD?

EC:F6:BD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SNCF MOBILITÉS. It covers every address from EC:F6:BD:00:00:00 to EC:F6:BD:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-F6-BD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:F6:BD:00:00:00 that is EC:F6:BD — 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 SNCF MOBILITÉS located?

SNCF MOBILITÉS is listed at 9 rue Jean-Philippe Rameau SAINT-DENIS FR 93200 in the IEEE OUI registry entry for EC:F6:BD. This is the address the organization registered with the IEEE, which may differ from its current operating address.
