<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>
