## Description

The NMSettingIP6Config object is a NMSetting subclass that describes properties related to IPv6 addressing, routing, and Domain Name Service

## Details

### NM_SETTING_IP6_CONFIG_MAY_FAIL

    #define NM_SETTING_IP6_CONFIG_MAY_FAIL           "may-fail"

### NM_SETTING_IP6_CONFIG_METHOD_IGNORE

    #define NM_SETTING_IP6_CONFIG_METHOD_IGNORE     "ignore"

IPv6 is not required or is handled by some other mechanism, and NetworkManager should not configure IPv6 for this connection.

### NM_SETTING_IP6_CONFIG_METHOD_AUTO

    #define NM_SETTING_IP6_CONFIG_METHOD_AUTO       "auto"

IPv6 configuration should be automatically determined via a method appropriate for the hardware interface, ie router advertisements, DHCP, or PPP or some other device-specific manner.

### NM_SETTING_IP6_CONFIG_METHOD_DHCP

    #define NM_SETTING_IP6_CONFIG_METHOD_DHCP       "dhcp"

IPv6 configuration should be automatically determined via DHCPv6 only and router advertisements should be ignored.

### NM_SETTING_IP6_CONFIG_METHOD_LINK_LOCAL

    #define NM_SETTING_IP6_CONFIG_METHOD_LINK_LOCAL "link-local"

IPv6 configuration should be automatically configured for link-local-only operation.

### NM_SETTING_IP6_CONFIG_METHOD_MANUAL

    #define NM_SETTING_IP6_CONFIG_METHOD_MANUAL     "manual"

All necessary IPv6 configuration (addresses, prefix, DNS, etc) is specified in the setting's properties.

### NM_SETTING_IP6_CONFIG_METHOD_SHARED

    #define NM_SETTING_IP6_CONFIG_METHOD_SHARED     "shared"

This connection specifies configuration that allows other computers to connect through it to the default network (usually the Internet). The connection's interface will be assigned a private address, and router advertisements, a caching DNS server, and Network Address Translation (NAT) functionality will be started on this connection's interface to allow other devices to connect through that interface to the default network. (not yet supported for IPv6)

### NMIP6Address

    typedef struct NMIP6Address NMIP6Address;

### nm_ip6_address_new ()

    NMIP6Address *      nm_ip6_address_new                  (void);

`address` : | the NMIP6Address
`other` : | the NMIP6Address to compare `address` to.
Returns : | `TRUE` if the objects contain the same values, `FALSE` if they do not.

## Property Details

### The `"addresses"` property

      "addresses"                GPtrArray_GValueArray_GArray_guchar_+guint+GArray_guchar___*  : Read / Write

Array of IPv6 address structures. Each IPv6 address structure is composed of 3 members, the first being a byte array containing the IPv6 address (network byte order), the second a 32-bit integer containing the IPv6 address prefix, and the third a byte array containing the IPv6 address (network byte order) of the gateway associated with this address, if any. If no gateway is given, the third element should be given as all zeros. For the 'auto' method, given IP addresses are appended to those returned by automatic configuration. Addresses cannot be used with the 'shared' or 'link-local' methods as the interface is automatically assigned an address with these methods.

### The `"dns"` property

      "dns"                      GPtrArray_GArray_guchar__*  : Read / Write

Array of DNS servers, where each member of the array is a byte array containing the IPv6 address of the DNS server (in 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' or 'link-local' 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' or 'link-local' 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' or 'dhcp' and this property is set 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' or 'dhcp' and this property is set 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 IPv6 configuration times out. Note that at least one IP configuration must succeed or overall network configuration will still fail. For example, in IPv4-only networks, setting this property to TRUE allows the overall network configuration to succeed if IPv6 configuration fails but IPv4 configuration completes successfully.

Default value: FALSE

### The `"method"` property

      "method"                   gchar*                : Read / Write

IPv6 configuration method. If 'auto' is specified then the appropriate automatic method (DHCP, PPP, advertisement, etc) is used for the interface and most other properties can be left unset. To force the use of DHCP only, specify 'dhcp'; this method is only valid for ethernet- based hardware. If 'link-local' is specified, then an IPv6 link-local address 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 'ignored' is specified, IPv6 configuration is not done. This property must be set. NOTE: the 'shared' method are not yet supported.

Default value: NULL

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

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

If TRUE, this connection will never be the default IPv6 connection, meaning it will never be assigned the default IPv6 route by NetworkManager.

Default value: FALSE

### The `"routes"` property

      "routes"                   GPtrArray_GValueArray_GArray_guchar_+guint+GArray_guchar_+guint__*  : Read / Write

Array of IPv6 route structures. Each IPv6 route structure is composed of 4 members; the first being the destination IPv6 network or address (network byte order) as a byte array, the second the destination network or address IPv6 prefix, the third being the next-hop IPv6 address (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' or 'link-local' methods because there is no upstream network.
