+ Network configuration
+
+
+
+ network.network
+
+
+
+ Description
+
+ Network setup is performed by
+ systemd-networkd8.
+
+
+ Network files must have the extension
+ .network; other extensions are ignored.
+ Networks are applied to links whenever the links appear.
+
+ The .network 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. All configuration files
+ are collectively sorted and processed in lexical order, regardless
+ of the directories in which they live. However, files with
+ identical filenames replace each other. Files in
+ /etc have the highest priority, files in
+ /run take precedence over files with the same
+ name in /usr/lib. This can be used to
+ override a system-supplied configuration file with a local file if
+ needed; a symlink in /etc with the same name
+ as a configuration file in /usr/lib, pointing
+ to /dev/null, disables the configuration file
+ entirely.
+
+
+
+
+ [Match] Section Options
+
+ The network file contains a [Match]
+ section, which determines if a given network file may be applied
+ to a given device; and a [Network] section
+ specifying how the device should be configured. The first (in
+ lexical order) of the network files that matches a given device
+ is applied.
+
+ A network file is said to match a device if each of the
+ entries in the [Match] section matches, or if
+ the section is empty. The following keys are accepted:
+
+
+
+ MACAddress=
+
+ The hardware address.
+
+
+
+ Path=
+
+ A whitespace-separated list of shell-style globs
+ matching the persistent path, as exposed by the udev
+ property ID_PATH.
+
+
+
+ Driver=
+
+ A whitespace-separated list of shell-style globs
+ matching the driver currently bound to the device, as
+ exposed by the udev property DRIVER
+ of its parent device, or if that is not set the driver
+ as exposed by ethtool -i of the
+ device itself.
+
+
+
+ Type=
+
+ A whitespace-separated list of shell-style globs
+ matching the device type, as exposed by the udev property
+ DEVTYPE.
+
+
+
+ Name=
+
+ A whitespace-separated list of shell-style globs
+ matching the device name, as exposed by the udev property
+ INTERFACE.
+
+
+
+ Host=
+
+ Matches against the hostname or machine ID of the
+ host. See ConditionHost= in
+ systemd.unit5
+ for details.
+
+
+
+
+ Virtualization=
+
+ Checks whether the system is executed in a virtualized
+ environment and optionally test whether it is a specific
+ implementation. See ConditionVirtualization= in
+ systemd.unit5
+ for details.
+
+
+
+
+ KernelCommandLine=
+
+ Checks whether a specific kernel command line option is
+ set (or if prefixed with the exclamation mark unset). See
+ ConditionKernelCommandLine= in
+ systemd.unit5
+ for details.
+
+
+
+
+ Architecture=
+
+ Checks whether the system is running on a specific
+ architecture. See ConditionArchitecture= in
+ systemd.unit5
+ for details.
+
+
+
+
+
+
+
+
+ [Link] Section Options
+
+ The [Link] section accepts the following keys:
+
+
+
+ MACAddress=
+
+ The hardware address.
+
+
+
+ MTUBytes=
+
+ The maximum transmission unit in bytes to set for the
+ device. The usual suffixes K, M, G, are supported and are
+ understood to the base of 1024.
+
+
+
+
+
+
+ [Network] Section Options
+
+ The [Network] section accepts the following keys:
+
+
+
+ Description=
+
+ A description of the device. This is only used for
+ presentation purposes.
+
+
+
+ DHCP=
+
+ Enables DHCPv4 and/or DHCPv6 support. Accepts
+ yes, no,
+ ipv4, or ipv6.
+
+
+
+ DHCPServer=
+
+ A boolean. Enables a basic DHCPv4 server on the
+ device. Mostly useful for handing out leases to container
+ instances.
+
+
+
+ LinkLocal=
+
+ Enables link-local address autoconfiguration. Accepts
+ yes, no,
+ ipv4, or ipv6. Defaults to
+ ipv6.
+
+
+
+ IPv4LLRoute=
+
+ A boolean. When true, sets up the route needed for
+ non-IPv4LL hosts to communicate with IPv4LL-only hosts. Defaults
+ to false.
+
+
+
+
+ IPv6Token=
+
+ An IPv6 address with the top 64 bits unset. When set, indicates the
+ 64 bits interface part of SLAAC IPv6 addresses for this link. By default
+ it is autogenerated.
+
+
+
+ LLMNR=
+
+ A boolean or resolve. When true, enables
+ Link-Local Multicast Name Resolution on the link, when set to
+ resolve only resolution is enabled, but not
+ announcement. Defaults to true.
+
+
+
+ LLDP=
+
+ A boolean. When true, enables LLDP link receive support.
+
+
+
+
+ Address=
+
+ A static IPv4 or IPv6 address and its prefix length,
+ separated by a / character. Specify
+ this key more than once to configure several addresses.
+ The format of the address must be as described in
+ inet_pton3.
+ This is a short-hand for an [Address] section only
+ containing an Address key (see below). This option may be
+ specified more than once.
+
+
+ If the specified address is 0.0.0.0 (for IPv4) or
+ [::] (for IPv6), a new address range of the requested size
+ is automatically allocated from a system-wide pool of
+ unused ranges. The allocated range is checked against all
+ current network interfaces and all known network
+ configuration files to avoid address range conflicts. The
+ default system-wide pool consists of 192.168.0.0/16,
+ 172.16.0.0/12 and 10.0.0.0/8 for IPv4, and fc00::/7 for
+ IPv6. This functionality is useful to manage a large
+ number of dynamically created network interfaces with the
+ same network configuration and automatic address range
+ assignment.
+
+
+
+
+ Gateway=
+
+ The gateway address, which must be in the format
+ described in

+
+
+
+ NTP=
+
+ An NTP server address. This option may be specified more than once.
+
+
+
+ IPForward=
+ Configures IP forwarding for the network
+ interface. If enabled incoming packets on the network
+ interface will be forwarded to other interfaces according to
+ the routing table. Takes either a boolean argument, or the
+ values ipv4 or ipv6,
+ which only enables IP forwarding for the specified address
+ family.
+
+
+ IPMasquerade=
+ Configures IP masquerading for the network
+ interface. If enabled packets forwarded from the network
+ interface will be appear as coming from the local host.
+ Takes a boolean argument. Implies
+ IPForward=yes.
+
