I am developing a program with Qt and I need to know if an IP is being used by a PC. How can I check the IP addresses that are being used in my network?
Unfortunately there is no reliable way to find all devices connected to a network.
What you can try is to use a service discovery framework like mdns to find other devices on the local network.
