Finding servers on network

Targets macOS
1

I’ve seen in apps, where it finds available Appservers in the same network. For example, when launching LiveTime Tkmer app, it shows me a list of LiveTime servers that I can connect to on the same network.

How would I go about doing this? Surely, the app is not pinging .1-.255 at a specific port?! That seems excessive. Is there a more efficient way?

Thanks!

For a LAN it might be using something like Bonjour or similar (zero conf networking)
