My understanding was that
sudo netstat -tlupn gives me all the addresses/ports that have processes listening and that
ip address list or
ifconfig (though I guess the latter is deprecated) would give all the network interfaces with their associated ip addresses. So what's up with
ip address list | grep 127.0.0.53
returning nothing when
sudo netstat -tlupn | grep 127.0.0.53
tcp 0 0 127.0.0.53:53 0.0.0.0:* LISTEN 714/systemd-resolve udp 0 0 127.0.0.53:53 0.0.0.0:* 714/systemd-resolve
Similar thing with
sudo netstat -tlupn | grep 188.8.131.52:
udp 0 0 184.108.40.206:5353 0.0.0.0:* 29533/chrome ...
What am I not understanding? (Running Ubuntu 18.04 inside VirtualBox fwiw).
