Which company owns MAC address prefix 08:D5:9D?

MAC address prefix 08:D5:9D is registered to Sagemcom Broadband SAS in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:D5:9D has a network interface built by Sagemcom Broadband SAS.

What is the OUI 08:D5:9D?

08:D5:9D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Sagemcom Broadband SAS. It covers every address from 08:D5:9D:00:00:00 to 08:D5:9D:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-D5-9D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 08:D5:9D:00:00:00 that is 08:D5:9D — 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 Sagemcom Broadband SAS located?

Sagemcom Broadband SAS is listed at 250, route de l'Empereur Rueil Malmaison Cedex hauts de seine FR 92848 in the IEEE OUI registry entry for 08:D5:9D. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Sagemcom Broadband SAS own?

Sagemcom Broadband SAS holds 219 OUI prefixes in the IEEE registry, of which 08:D5:9D is one. A device made by Sagemcom Broadband SAS could carry a MAC address from any of them.
