Which company owns MAC address prefix D8:0C:CF?

MAC address prefix D8:0C:CF is registered to C.G.V. S.A.S. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D8:0C:CF has a network interface built by C.G.V. S.A.S..

What is the OUI D8:0C:CF?

D8:0C:CF is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to C.G.V. S.A.S.. It covers every address from D8:0C:CF:00:00:00 to D8:0C:CF:FF:FF:FF, or 16,777,216 addresses in total. It is also written D8-0C-CF.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D8:0C:CF:00:00:00 that is D8:0C:CF — 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 C.G.V. S.A.S. located?

C.G.V. S.A.S. is listed at 18, RUE THEODORE MONOD OSTWALD CEDEX BAS-RHIN FR 67541 in the IEEE OUI registry entry for D8:0C:CF. This is the address the organization registered with the IEEE, which may differ from its current operating address.

C.G.V. S.A.S.

MAC address prefix D8:0C:CF is registered to C.G.V. S.A.S. in the IEEE OUI registry. Any device whose MAC address begins with D8:0C:CF has a network interface built by C.G.V. S.A.S.. 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 D8:0C:CF:00:00:00 to D8:0C:CF:FF:FF:FF.
