Do not edit. # # This is a static resolv.conf file for connecting local clients to the # internal DNS stub resolver of systemd-resolved. This file lists no search # domains. # # Run "systemd-resolve --status" to see details about the uplink DNS servers # currently in use. # # Third party programs must not access this file directly, but only through the # symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a different way, # replace this symlink by a static file or a different symlink. # # See man:systemd-resolved.service(8) for details about the supported modes of # operation for /etc/resolv.conf. nameserver 127.0.0.1 nameserver 127.0.0.53 Restart DNSMasq systemctl restart dnsmasq
