  58
  59     <para><command>systemd-resolved</command> is a system service that
  60     manages network name resolution. It implements a caching DNS stub
  61     resolver and an LLMNR resolver and responder. It also generates
  62     <filename>/run/systemd/resolve/resolv.conf</filename> for
  63     compatibility which may be symlinked from
  64     <filename>/etc/resolv.conf</filename>.</para>
  65
  66     <para>The DNS servers contacted are determined from the global
  67     settings in
  68     <citerefentry><refentrytitle>resolved.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
  69     the per-link static settings in <filename>.network</filename>
  70     files, and the per-link dynamic settings received over DHCP. See
  71     <citerefentry><refentrytitle>systemd.network</refentrytitle><manvolnum>5</manvolnum></citerefentry>
  72     for more details.</para>
  73
  74     <para>Note that
  75     <filename>/run/systemd/resolve/resolv.conf</filename> should not
  76     be used directly, but only through a symlink from
  77     <filename>/etc/resolv.conf</filename>.</para>
