Which company owns MAC address prefix 2C:17:E0?

MAC address prefix 2C:17:E0 is registered to SYSTEMES ET TECHNOLOGIES IDENTIFICATION (STid) in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 2C:17:E0 has a network interface built by SYSTEMES ET TECHNOLOGIES IDENTIFICATION (STid).

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 2C:17:E0:00:00:00 that is 2C:17:E0 — 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.

SYSTEMES ET TECHNOLOGIES IDENTIFICATION (STid)

MAC address prefix 2C:17:E0 is registered to SYSTEMES ET TECHNOLOGIES IDENTIFICATION (STid) in the IEEE OUI registry. Any device whose MAC address begins with 2C:17:E0 has a network interface built by SYSTEMES ET TECHNOLOGIES IDENTIFICATION (STid). This prefix (the OUI, or Organizationally Unique Identifier) is assigned by the IEEE and is the first three octets of the address — it covers every MAC from 2C:17:E0:00:00:00 to 2C:17:E0:FF:FF:FF.
