## Property Details

### The `"addresses"` property

      "addresses"                GPtrArray_GArray_guint__*  : Read / Write

Array of IPv4 address structures. Each IPv4 address structure is composed of 3 32-bit values; the first being the IPv4 address (network byte order), the second the prefix (1 - 32), and last the IPv4 gateway (network byte order). The gateway may be left as 0 if no gateway exists for that subnet. For the 'auto' method, given IP addresses are appended to those returned by automatic configuration. Addresses cannot be used with the 'shared', 'link-local', or 'disabled' methods as addressing is either automatic or disabled with these methods.

### The `"dhcp-client-id"` property

      "dhcp-client-id"           gchar*                : Read / Write

A string sent to the DHCP server to identify the local machine which the DHCP server may use to cusomize the DHCP lease and options.

Default value: NULL

### The `"dhcp-hostname"` property

      "dhcp-hostname"            gchar*                : Read / Write

If the "dhcp-send-hostname" property is TRUE, then the specified name will be sent to the DHCP server when acquiring a lease.

Default value: NULL

### The `"dhcp-send-hostname"` property

      "dhcp-send-hostname"       gboolean              : Read / Write / Construct

If TRUE, a hostname is sent to the DHCP server when acquiring a lease. Some DHCP servers use this hostname to update DNS databases, essentially providing a static hostname for the computer. If "dhcp-hostname" is empty and this property is TRUE, the current persistent hostname of the computer is sent.

Default value: TRUE

### The `"dns"` property

      "dns"                      GArray_guint_*        : Read / Write

List of DNS servers (network byte order). For the 'auto' method, these DNS servers are appended to those (if any) returned by automatic configuration. DNS servers cannot be used with the 'shared', 'link-local', or 'disabled' methods as there is no usptream network. In all other methods, these DNS servers are used as the only DNS servers for this connection.

### The `"dns-search"` property

      "dns-search"               GSList_gchararray_*   : Read / Write

List of DNS search domains. For the 'auto' method, these search domains are appended to those returned by automatic configuration. Search domains cannot be used with the 'shared', 'link-local', or 'disabled' methods as there is no upstream network. In all other methods, these search domains are used as the only search domains for this connection.

### The `"ignore-auto-dns"` property

      "ignore-auto-dns"          gboolean              : Read / Write / Construct

When the method is set to 'auto' and this property to TRUE, automatically configured nameservers and search domains are ignored and only nameservers and search domains specified in "dns" and "dns-search", if any, are used.

Default value: FALSE

### The `"ignore-auto-routes"` property

      "ignore-auto-routes"       gboolean              : Read / Write / Construct

When the method is set to 'auto' and this property to TRUE, automatically configured routes are ignored and only routes specified in "routes", if any, are used.

Default value: FALSE

### The `"may-fail"` property

      "may-fail"                 gboolean              : Read / Write / Construct

If TRUE, allow overall network configuration to proceed even if IPv4 configuration times out. Note that at least one IP configuration must succeed or overall network configuration will still fail. For example, in IPv6-only networks, setting this property to TRUE allows the overall network configuration to succeed if IPv4 configuration fails but IPv6 configuration completes successfully.

Default value: FALSE

### The `"method"` property

      "method"                   gchar*                : Read / Write

IPv4 configuration method. 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. This property must be set.

Default value: NULL

### The `"never-default"` property

      "never-default"            gboolean              : Read / Write / Construct

If TRUE, this connection will never be the default IPv4 connection, meaning it will never be assigned the default route by NetworkManager.

Default value: FALSE

### The `"routes"` property

      "routes"                   GPtrArray_GArray_guint__*  : Read / Write

Array of IPv4 route structures. Each IPv4 route structure is composed of 4 32-bit values; the first being the destination IPv4 network or address (network byte order), the second the destination network or address prefix (1 - 32), the third being the next-hop (network byte order) if any, and the fourth being the route metric. For the 'auto' method, given IP routes are appended to those returned by automatic configuration. Routes cannot be used with the 'shared', 'link-local', or 'disabled' methods because there is no upstream network.
