Which company owns MAC address prefix 20:9E:79?

MAC address prefix 20:9E:79 is registered to Universal Electronics, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 20:9E:79 has a network interface built by Universal Electronics, Inc..

What is the OUI 20:9E:79?

20:9E:79 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Universal Electronics, Inc.. It covers every address from 20:9E:79:00:00:00 to 20:9E:79:FF:FF:FF, or 16,777,216 addresses in total. It is also written 20-9E-79.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 20:9E:79:00:00:00 that is 20:9E:79 — 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 Universal Electronics, Inc. located?

Universal Electronics, Inc. is listed at 201 E. Sandpointe Ave Santa Ana CA US 92707 in the IEEE OUI registry entry for 20:9E:79. This is the address the organization registered with the IEEE, which may differ from its current operating address.
