Which company owns MAC address prefix 20:19:F3?

MAC address prefix 20:19:F3 is registered to WavTek Technologies, Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 20:19:F3 has a network interface built by WavTek Technologies, Inc.

What is the OUI 20:19:F3?

20:19:F3 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to WavTek Technologies, Inc. It covers every address from 20:19:F3:00:00:00 to 20:19:F3:FF:FF:FF, or 16,777,216 addresses in total. It is also written 20-19-F3.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 20:19:F3:00:00:00 that is 20:19:F3 — 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 WavTek Technologies, Inc located?

WavTek Technologies, Inc is listed at 224 S Main St Unit 135 Springville UT US 84043 in the IEEE OUI registry entry for 20:19:F3. This is the address the organization registered with the IEEE, which may differ from its current operating address.
