It doesn't cover in detail how to use mitmproxy / wireshark (SYN, SYN-ACK, ACK, FIN ...) etc., but it's enough to get an idea of what your devices are doing in your own network.
Use Wireshark world map option to see which countries your devices/software connect to.
It also gives you more information to improve your [firewall](https://wiki.digitalprivacy.diy/en/server/services/firewalld) or [DNS blocklist](https://wiki.digitalprivacy.diy/en/server/services/adguardhome).
