Which company owns MAC address prefix C4:10:8A?

MAC address prefix C4:10:8A is registered to Ruckus Wireless in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C4:10:8A has a network interface built by Ruckus Wireless.

What is the OUI C4:10:8A?

C4:10:8A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ruckus Wireless. It covers every address from C4:10:8A:00:00:00 to C4:10:8A:FF:FF:FF, or 16,777,216 addresses in total. It is also written C4-10-8A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C4:10:8A:00:00:00 that is C4:10:8A — 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 Ruckus Wireless located?

Ruckus Wireless is listed at 350 West Java Drive Sunnyvale CA US 94089 in the IEEE OUI registry entry for C4:10:8A. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Ruckus Wireless own?

Ruckus Wireless holds 100 OUI prefixes in the IEEE registry, of which C4:10:8A is one. A device made by Ruckus Wireless could carry a MAC address from any of them.
