Which company owns MAC address prefix B4:02:F2?

MAC address prefix B4:02:F2 is registered to Synaptics, Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B4:02:F2 has a network interface built by Synaptics, Inc.

What is the OUI B4:02:F2?

B4:02:F2 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 B4:02:F2:00:00:00 to B4:02:F2:FF:FF:FF, or 16,777,216 addresses in total. It is also written B4-02-F2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B4:02:F2:00:00:00 that is B4:02:F2 — 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 B4:02:F2. 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 B4:02:F2 is one. A device made by Synaptics, Inc could carry a MAC address from any of them.
