<term><varname>DNS=</varname></term>
<listitem><para>A space separated list of IPv4 and IPv6
addresses to be used as system DNS servers. DNS requests are
sent to one of the listed DNS servers in parallel to any
per-interface DNS servers acquired from
<citerefentry><refentrytitle>systemd-networkd.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
For compatibility reasons, if set to the empty list the DNS
servers listed in <filename>/etc/resolv.conf</filename> are
used, if any are configured there. This setting defaults to
the empty list.</para></listitem>

<term><varname>FallbackDNS=</varname></term>
<listitem><para>A space separated list of IPv4 and IPv6
addresses to be used as the fallback DNS servers. Any
per-interface DNS servers obtained from
<citerefentry><refentrytitle>systemd-networkd.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>
take precedence over this setting, as do any servers set via
<varname>DNS=</varname> above or
<filename>/etc/resolv.conf</filename>. This setting is hence
only used if no other DNS server information is known. If this
option is not given, a compiled-in list of DNS servers is used
instead.</para></listitem>

<listitem><para>Takes a boolean argument or
<literal>resolve</literal>. Controls Link-Local Multicast Name
Resolution support (<ulink

the local host. If true enables full LLMNR responder and
resolver support. If false disable both. If set to
<literal>resolve</literal> only resolving support is enabled,
but responding is disabled. Note that
<citerefentry><refentrytitle>systemd-networkd.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>
also maintains per-interface LLMNR settings. LLMNR will be
enabled on an interface only if the per-interface and the
