Which company owns MAC address prefix C4:4F:D5?

MAC address prefix C4:4F:D5 is registered to Vantiva - Connected Home in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C4:4F:D5 has a network interface built by Vantiva - Connected Home.

What is the OUI C4:4F:D5?

C4:4F:D5 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Vantiva - Connected Home. It covers every address from C4:4F:D5:00:00:00 to C4:4F:D5:FF:FF:FF, or 16,777,216 addresses in total. It is also written C4-4F-D5.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C4:4F:D5:00:00:00 that is C4:4F:D5 — 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 Vantiva - Connected Home located?

Vantiva - Connected Home is listed at 4855 Peachtree Industrial Blvd, Suite 200 Norcross GA US 30902 in the IEEE OUI registry entry for C4:4F:D5. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Vantiva - Connected Home own?

Vantiva - Connected Home holds 7 OUI prefixes in the IEEE registry, of which C4:4F:D5 is one. A device made by Vantiva - Connected Home could carry a MAC address from any of them.
