Cool idea!
I replaced the "teller" program part also with shell script, so that one would give you the clicking without the need to compile:
sudo tcpdump -n -l dst host 8.8.8.8 $(for a in $(curl -s https://raw.githubusercontent.com/berthubert/googerteller/main/goog-prefixes.txt); do echo or dst net $a; done) | while read; do paplay /usr/share/sounds/freedesktop/stereo/dialog-information.oga; done
