Which company owns MAC address prefix 94:FA:57?

MAC address prefix 94:FA:57 is registered to Equalizer Technologies in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 94:FA:57 has a network interface built by Equalizer Technologies.

What is the OUI 94:FA:57?

94:FA:57 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Equalizer Technologies. It covers every address from 94:FA:57:00:00:00 to 94:FA:57:FF:FF:FF, or 16,777,216 addresses in total. It is also written 94-FA-57.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 94:FA:57:00:00:00 that is 94:FA:57 — 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 Equalizer Technologies located?

Equalizer Technologies is listed at Room 6 2/F, One Vista Summit, 3 San Hop Lane, Tuen Mun Hong Kong HK NA in the IEEE OUI registry entry for 94:FA:57. This is the address the organization registered with the IEEE, which may differ from its current operating address.
