Which company owns MAC address prefix 9C:A1:0A?

MAC address prefix 9C:A1:0A is registered to SCLE SFE in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 9C:A1:0A has a network interface built by SCLE SFE.

What is the OUI 9C:A1:0A?

9C:A1:0A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SCLE SFE. It covers every address from 9C:A1:0A:00:00:00 to 9C:A1:0A:FF:FF:FF, or 16,777,216 addresses in total. It is also written 9C-A1-0A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 9C:A1:0A:00:00:00 that is 9C:A1:0A — 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 SCLE SFE located?

SCLE SFE is listed at Parc des Aygalades – Bât 10 MARSEILLE PACA FR 13014 in the IEEE OUI registry entry for 9C:A1:0A. This is the address the organization registered with the IEEE, which may differ from its current operating address.

SCLE SFE

MAC address prefix 9C:A1:0A is registered to SCLE SFE in the IEEE OUI registry. Any device whose MAC address begins with 9C:A1:0A has a network interface built by SCLE SFE. 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 9C:A1:0A:00:00:00 to 9C:A1:0A:FF:FF:FF.
