Sonos device on my network
Sonos is an American maker of networked speakers and home audio systems.
What Sonos makes
Sonos makes wireless speakers, soundbars, subwoofers and amplifiers that play music over Wi-Fi and are controlled through the Sonos app.
What the device on your network probably is
Almost certainly a Sonos speaker, soundbar, sub or amp. A home with several Sonos products will show several entries.
How to work out which device it is
In the Sonos app, open the system settings and each product's About page to see its IP and MAC address. Unplugging a speaker makes its entry disappear.
Should you be worried
Nothing to worry about: it is a Sonos speaker in your home.
The app finds every device on the Wi-Fi you are on, at home or in a rental, and puts the vendor next to the hostname, the services it advertises and its open ports, which together usually name the product. Where it cannot tell, it says so instead of guessing. Get RECON for iPhone — one-time purchase, no account, nothing leaves the device.
