  58
  59                 <para><command>systemd-resolved</command> is a system
  60                 service that manages network name resolution. It
  61                 implements a caching DNS stub resolver and an LLMNR
  62                 resolver and responder. It also generates
  63                 <filename>/run/systemd/resolve/resolv.conf</filename>
  64                 for compatibility which may be symlinked from
  65                 <filename>/etc/resolv.conf</filename>.</para>
  66
  67                 <para>The DNS servers contacted are determined from
  68                 the global settings in
  69                 <citerefentry><refentrytitle>resolved.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
  70                 the per-link static settings in
  71                 <filename>.network</filename> files, and the per-link
  72                 dynamic settings received over DHCP. See
  73                 <citerefentry><refentrytitle>systemd.network</refentrytitle><manvolnum>5</manvolnum></citerefentry>
