Which company owns MAC address prefix 90:CC:24?

MAC address prefix 90:CC:24 is registered to Synaptics, Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 90:CC:24 has a network interface built by Synaptics, Inc.

What is the OUI 90:CC:24?

90:CC:24 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Synaptics, Inc. It covers every address from 90:CC:24:00:00:00 to 90:CC:24:FF:FF:FF, or 16,777,216 addresses in total. It is also written 90-CC-24.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 90:CC:24:00:00:00 that is 90:CC:24 — 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 Synaptics, Inc located?

Synaptics, Inc is listed at 1251 McKay Drive San Jose CA US 95131-1709 in the IEEE OUI registry entry for 90:CC:24. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Synaptics, Inc own?

Synaptics, Inc holds 3 OUI prefixes in the IEEE registry, of which 90:CC:24 is one. A device made by Synaptics, Inc could carry a MAC address from any of them.
