Which company owns MAC address prefix 24:D6:60?

MAC address prefix 24:D6:60 is registered to Silicon Laboratories in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 24:D6:60 has a network interface built by Silicon Laboratories.

What is the OUI 24:D6:60?

24:D6:60 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Silicon Laboratories. It covers every address from 24:D6:60:00:00:00 to 24:D6:60:FF:FF:FF, or 16,777,216 addresses in total. It is also written 24-D6-60.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 24:D6:60:00:00:00 that is 24:D6:60 — 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 Silicon Laboratories located?

Silicon Laboratories is listed at 400 West Cesar Chavez Austin TX US 78701 in the IEEE OUI registry entry for 24:D6:60. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Silicon Laboratories own?

Silicon Laboratories holds 156 OUI prefixes in the IEEE registry, of which 24:D6:60 is one. A device made by Silicon Laboratories could carry a MAC address from any of them.
