<title>Description</title>
<para><command>systemd-networkd</command> is a system
service that manages networks. It detects and configures
network devices as they appear, as well as creating virtual
network devices.</para>
<para>To configure low-level link settings independently of
networks, see
<citerefentry><refentrytitle>systemd.link</refentrytitle><manvolnum>5</manvolnum></citerefentry>
.</para>
<para>Network configurations applied before networkd is started
are not removed, and static configuration applied by networkd
is not removed when networkd exits. Dynamic configuration applied by
networkd may also optionally be left in place on shut-down. This ensures
restarting networkd does not cut the network connection, and, in particular,
that it is safe to transition between the initrd and the real root,
and back.</para>
<para>Nameservers configured in networkd, or receievd over DHCP
are exposed in <filename>/run/systemd/network/resolv.conf</filename>.
This file should not be used directly, but only through a symlink
from <filename>/etc/resolv.conf</filename>.</para>
</refsect1>
<refsect1><title>Configuration Files</title>
<para>The configuration files are read from the files located in the
system network directory <filename>/usr/lib/systemd/network</filename>,
the volatile runtime network directory
<filename>/run/systemd/network</filename> and the local administration
network directory <filename>/etc/systemd/network</filename>.</para>
<para>Networks are configured in <filename>.network</filename> files, see
<citerefentry><refentrytitle>systemd.network</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
and virtual network devices are configured in <filename>.netdev</filename> files, see
<citerefentry><refentrytitle>systemd.netdev</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
