# This is /run/systemd/resolve/stub-resolv.conf managed by man:systemd-resolved(8). # Do not edit. # # This file might be symlinked as /etc/resolv.conf. If you're looking at # /etc/resolv.conf and seeing this text, you have followed the symlink. # # This is a dynamic resolv.conf file for connecting local clients to the # internal DNS stub resolver of systemd-resolved. This file lists all # configured search domains. # # Run "resolvectl status" to see details about the uplink DNS servers # currently in use. # # Third party programs should typically 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.
