How to find out ip through P2P calls?

Question

Web development

Hi all! Please tell me how can I find out which ip my ip sends a request to when making a P2P call?
Knowing that it is possible to find out ip in this way, telegrams made it possible for users themselves to choose p2p in the settings.
I would be grateful for help. The implementation itself is interesting for informational purposes (considering that this feature is disabled for many applications).

Try installing Wireshark, a great program that, if you get used to it, shows the packets and the data itself of all outgoing and incoming traffic with filters. You can even learn sockets from it, not only see where.
Or there is an easier option - open an antivirus and see where the network is loaded when the program is running, the address and port are usually written there.
