systemd-networkd is a system service that manages networks. It
detects and configures network devices as they appear, as well as
creating virtual network devices.
To configure low-level link settings independently of networks, see
systemd.link(5).
systemd-networkd will create network devices based on the
configuration in systemd.netdev(5) files, respecting the [Match]
sections in those files.
systemd-networkd will manage network addresses and routes for any
link for which it finds a .network file with an appropriate [Match]
section, see systemd.network(5). For those links, it will flush
existing network addresses and routes when bringing up the device.
Any links not matched by one of the .network files will be ignored.
It is also possible to explicitly tell systemd-networkd to ignore a
link by using Unmanaged=yes option, see systemd.network(5).
When systemd-networkd exits, it generally leaves existing network
devices and configuration intact. This makes it possible to
transition from the initramfs and to restart the service without
breaking connectivity. This also means that when configuration is
updated and systemd-networkd is restarted, netdev interfaces for
which configuration was removed will not be dropped, and may need to
be cleaned up manually.
systemd-networkd may be introspected and controlled at runtime using
networkctl(1).
The configuration files are read from the files located in the system
network directory /usr/lib/systemd/network, the volatile runtime
network directory /run/systemd/network and the local administration
network directory /etc/systemd/network.
Networks are configured in .network files, see systemd.network(5),
and virtual network devices are configured in .netdev files, see
systemd.netdev(5).
