Hi @milewap, 16.04 really hides their DNS servers behind dnsmasq, networkmanager and early systemd-resolve. I get rid of those personally but in a stock VM I did find this info works:

nmcli device show | grep DNS

This is changing in later versions like 17.04 when systemd-resolve takes over dnsmasq local caching server.

I olso @Bill_MI right now,i found type this cat /etc/resolv.conf and you see dns.My terminal right now after cat /etc/resolv.conf [email protected]:~$ cat /etc/resolv.conf

Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)


nameserver [email protected]:~$

Olso on this link you find how to prevent overwriting hmmmm maybe also this link is useful .Whatever I’m successful chaged dns,and now i am back onlayn :slight_smile:
