<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>

<listitem > <para > A space separated list

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

<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

used instead.</para> </listitem>

Link-Local Multicast Name Resolution support (<ulink

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
