Use dnsmasq for DNS

As the name already implies, dnsmasq is not a full-fledged DNS server. If you want a real, recursive DNS resolver, consider using unbound instead. 

 Install dnsmasq 

 dnsmasq is available on SailfishOS chum. You 1st need to add the 3rd-party-repo, afterwards running devel-su pkcon refresh && pkcon install dnsmasq will install it. 

 Disable your current DNS handler 

 On a fresh installation, DNS is handled by connman . You can remove it with these instructions . 

 Permanently run dnsmasq on boot 

 Execute  devel-su systemctl enable --now dnsmasq to enable it permanently & start it now. 

 Configure dnsmasq 

 dnsmasq's configuration lies under /etc/dnsmasq.conf . You can get more information about its config options from dnsmasq's manpage and ArchWiki .
