    <title>Description</title>

    <para><command>systemd-resolved</command> is a system service that
    manages network name resolution. It implements a caching DNS stub
    resolver and an LLMNR resolver and responder. It also generates
    <filename>/run/systemd/resolve/resolv.conf</filename> for
    compatibility which may be symlinked from
    <filename>/etc/resolv.conf</filename>.</para>

    <para>The DNS servers contacted are determined from the global
    settings in
    <citerefentry><refentrytitle>resolved.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
    the per-link static settings in <filename>.network</filename>
    files, and the per-link dynamic settings received over DHCP. See
    <citerefentry><refentrytitle>systemd.network</refentrytitle><manvolnum>5</manvolnum></citerefentry>
    for more details.</para>

    <para>Note that
    <filename>/run/systemd/resolve/resolv.conf</filename> should not
    be used directly, but only through a symlink from
    <filename>/etc/resolv.conf</filename>.</para>
