+ * SECTION:nm-setting-ip4-config
+ * @short_description: Describes IPv4 addressing, routing, and name service properties
+ *
+ * The #NMSettingIP4Config object is a #NMSetting subclass that describes
+ * properties related to IPv4 addressing, routing, and Domain Name Service.
+ *
+ * #NMSettingIP4Config has few properties or methods of its own; it inherits
+ * almost everything from #NMSettingIPConfig.
+ *
+ * NetworkManager supports 5 values for the #NMSettingIPConfig:method property
+ * for IPv4.  If "auto" is specified then the appropriate automatic method
+ * (DHCP, PPP, etc) is used for the interface and most other properties can be
+ * left unset.  If "link-local" is specified, then a link-local address in the
+ * 169.254/16 range will be assigned to the interface.  If "manual" is
+ * specified, static IP addressing is used and at least one IP address must be
+ * given in the "addresses" property.  If "shared" is specified (indicating that
+ * this connection will provide network access to other computers) then the
+ * interface is assigned an address in the 10.42.x.1/24 range and a DHCP and
+ * forwarding DNS server are started, and the interface is NAT-ed to the current
+ * default network connection.  "disabled" means IPv4 will not be used on this
+ * connection.

+     * 'type' field as per RFC 2132 section 9.14 and the remaining bytes may be
+     * an hardware address (e.g. '01:xx:xx:xx:xx:xx:xx' where 1 is the Ethernet
+     * ARP type and the rest is a MAC address).
+     * If the property is not a hex string it is considered as a
+     * non-hardware-address client ID and the 'type' field is set to 0.
+     *
+     * The special values "mac" and "perm-mac" are supported, which use the
+     * current or permanent MAC address of the device to generate a client identifier
+     * with type ethernet (01). Currently, these options only work for ethernet
+     * type of links.
+     *
+     * The special value "ipv6-duid" uses the DUID from "ipv6.dhcp-duid" property as
+     * an RFC4361-compliant client identifier. As IAID it uses "ipv4.dhcp-iaid"
+     * and falls back to "ipv6.dhcp-iaid" if unset.
+     *
+     * The special value "duid" generates a RFC4361-compliant client identifier based
+     * on "ipv4.dhcp-iaid" and uses a DUID generated by hashing /etc/machine-id.
+     *
+     * The special value "stable" is supported to generate a type 0 client identifier based
+     * on the stable-id (see connection.stable-id) and a per-host key. If you set the
+     * stable-id, you may want to include the "${DEVICE}" or "${MAC}" specifier to get a
+     * per-device key.
