<varlistentry>

<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>

</varlistentry>

<varlistentry>

<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>

</varlistentry>

<varlistentry>

<term><varname>LLMNR=</varname></term>

<listitem><para>Takes a boolean argument or

<literal>resolve</literal>. Controls Link-Local Multicast Name

Resolution support (<ulink

url="https://tools.ietf.org/html/rfc4795">RFC 4794</ulink>) on

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

global setting is on.</para></listitem>
