I have some questions regarding name resolution system in 17.04. <div class="post-text" itemprop="text"> After upgrading to 17.04 from 16.04 I can't figure out how host name resolution system is meant to be configured. First, I've noticed that after upgrade search domains have disappeared from <code>/etc/resolv.conf</code>. They came back once I've removed <code>/etc/resolv.conf</code> symlink and restarted NetworkManager. But then the contents became as follows: <pre><code># Generated by NetworkManager search mydomain1 mydomain2 nameserver 127.0.1.1 </code></pre> Ok, search domains are there. But why nameserver 127.0.1.1 is there? No process is listening on that address, hence the name resolution doesn't work. AFAIK, 127.0.1.1 is the hard-coded listen address of dnsmasq, which is not configured in <code>/etc/NetworkManager/NetworkManager.conf</code>: <pre><code>[main] plugins=ifupdown,keyfile [ifupdown] managed=false [logging] level=DEBUG </code></pre> Actually, dnsmasq wasn't even installed after upgrade. After installing dnsmasq and adding the line <code>dns=dnsmasq</code> into <code>NetworkManager.conf</code>, everything works well, but I wonder if I am doing something wrong, or is it a bug in NetworkManager or somewhere else. So my questions are, is it possible to use systemd-resolved instead of dnsmasq? If not, what is the purpose of moving to systemd-resolved? </div> </body> </html>
