Who owns the MAC starting with 00:40:A1?
The first three blocks of a MAC address form the OUI (Organizationally Unique Identifier), a code the IEEE assigns to each manufacturer. The prefix 00:40:A1 is registered to ERGO COMPUTING. Any device whose MAC starts with 00:40:A1 (for example, 00:40:A1:1A:2B:3C) was made by this company.
What it means to see this device on your network
Knowing the manufacturer helps identify what is connected to your Wi-Fi or company network. A ERGO COMPUTING MAC you don't recognize could be a legitimate device (a phone, a TV, a camera) — or one that shouldn't be there.
How to see every device and vendor on your network
Looking up one MAC vendor at a time is tedious. Sentinela, by PC Monitor, automatically maps every device on your network, shows each one's vendor by MAC and flags suspicious devices and connections — running on your Windows. Meet Sentinela.
