## Includes

    #include <nm-setting-ip-config.h>

## Description

NMSettingIPConfig is the abstract base class of NMSettingIP4Config and NMSettingIP6Config, providing properties related to IP addressing, routing, and Domain Name Service.

## Functions

### nm_ip_address_new ()

    NMIPAddress *
    nm_ip_address_new (int family,
                       const char *addr,
                       guint prefix,
                       GError **error);

Creates a new NMIPAddress object.

#### Parameters

family | the IP address family (`AF_INET` or `AF_INET6`) |
addr | the IP address |
prefix | the address prefix length |
error | location to store error, or `NULL` |

#### Returns

the new NMIPAddress object, or `NULL` on error.

### nm_ip_address_new_binary ()

    NMIPAddress *
    nm_ip_address_new_binary (int family,
                              gconstpointer addr,
                              guint prefix,
                              GError **error);

Creates a new NMIPAddress object. `addr` must point to a buffer of the correct size for `family` .

#### Parameters

family | the IP address family (`AF_INET` or `AF_INET6`) |
addr | the IP address |
prefix | the address prefix length |
error | location to store error, or `NULL` |

#### Returns

the new NMIPAddress object, or `NULL` on error.

[transfer full]

### nm_ip_address_ref ()

    void
    nm_ip_address_ref (NMIPAddress *address);

Increases the reference count of the object.

#### Parameters

address | the NMIPAddress |

### nm_ip_address_unref ()

    void
    nm_ip_address_unref (NMIPAddress *address);

Decreases the reference count of the object. If the reference count reaches zero, the object will be destroyed.

#### Parameters

address | the NMIPAddress |

### nm_ip_address_equal ()

    gboolean
    nm_ip_address_equal (NMIPAddress *address,
                         NMIPAddress *other);

Determines if two NMIPAddress objects contain the same address and prefix (attributes are not compared).

#### Parameters

address | the NMIPAddress |
other | the NMIPAddress to compare `address` to. |

#### Returns

`TRUE` if the objects contain the same values, `FALSE` if they do not.

### nm_ip_address_cmp_full ()

    int
    nm_ip_address_cmp_full (const NMIPAddress *a,
                            const NMIPAddress *b,
                            NMIPAddressCmpFlags cmp_flags);

Note that with `cmp_flags` NM_IP_ADDRESS_CMP_FLAGS_WITH_ATTRS, there is no total order for comparing GVariant. That means, if the two addresses only differ by their attributes, the sort order is undefined and the return value only indicates equality.

#### Parameters

a | the NMIPAddress |
b | the NMIPAddress to compare `address` to. |
cmp_flags | the NMIPAddressCmpFlags that indicate what to compare. |

#### Returns

0 if the two objects have the same values (according to their flags) or a integer indicating the compare order.

Creates a copy of `address`

#### Parameters

address | the NMIPAddress |

#### Returns

a copy of `address`

## Types and Values

### NM_IP_ADDRESS_ATTRIBUTE_LABEL

    #define NM_IP_ADDRESS_ATTRIBUTE_LABEL "label"

### enum NMIPAddressCmpFlags

Compare flags for `nm_ip_address_cmp_full()`.

#### Members

NM_IP_ADDRESS_CMP_FLAGS_NONE | no flags. |
NM_IP_ADDRESS_CMP_FLAGS_WITH_ATTRS | when comparing two addresses, also consider their attributes. Warning: note that attributes are GVariants and they don't have a total order. In other words, if the address differs only by their attributes, the returned compare order is not total. In that case, the return value merely indicates equality (zero) or inequality. |

### enum NMDhcpHostnameFlags

NMDhcpHostnameFlags describe flags related to the DHCP hostname and FQDN.

#### Members

NM_DHCP_HOSTNAME_FLAG_NONE | no flag set. The default value from Networkmanager global configuration is used. If such value is unset or still zero, the DHCP request will use standard FQDN flags, i.e. `NM_DHCP_HOSTNAME_FLAG_FQDN_SERV_UPDATE` and `NM_DHCP_HOSTNAME_FLAG_FQDN_ENCODED` for IPv4 and `NM_DHCP_HOSTNAME_FLAG_FQDN_SERV_UPDATE` for IPv6. |
NM_DHCP_HOSTNAME_FLAG_FQDN_SERV_UPDATE | whether the server should do the A RR (FQDN-to-address) DNS updates. |
NM_DHCP_HOSTNAME_FLAG_FQDN_ENCODED | if set, the FQDN is encoded using canonical wire format. Otherwise it uses the deprecated ASCII encoding. This flag is allowed only for DHCPv4. |
NM_DHCP_HOSTNAME_FLAG_FQDN_NO_UPDATE | when not set, request the server to perform updates (the PTR RR and possibly the A RR based on the `NM_DHCP_HOSTNAME_FLAG_FQDN_SERV_UPDATE` flag). If this is set, the `NM_DHCP_HOSTNAME_FLAG_FQDN_SERV_UPDATE` flag should be cleared. |
NM_DHCP_HOSTNAME_FLAG_FQDN_CLEAR_FLAGS | when set, no FQDN flags are sent in the DHCP FQDN option. When cleared and all other FQDN flags are zero, standard FQDN flags are sent. This flag is incompatible with any other FQDN flag. |
