QHostAddress::Null | 0 | The null address object. Equivalent to QHostAddress(). |
QHostAddress::LocalHost | 2 | The IPv4 localhost address. Equivalent to QHostAddress("127.0.0.1"). |
QHostAddress::LocalHostIPv6 | 3 | The IPv6 localhost address. Equivalent to QHostAddress("::1"). |
QHostAddress::Broadcast | 1 | The IPv4 broadcast address. Equivalent to QHostAddress("255.255.255.255"). |
QHostAddress::Any | 4 | The IPv4 any-address. Equivalent to QHostAddress("0.0.0.0"). |
QHostAddress::AnyIPv6 | 5 | The IPv6 any-address. Equivalent to QHostAddress("::"). |
Constructs a host address object with the IP address 0.0.0.0.
See also clear().
Constructs a host address object with the IPv4 address ip4Addr.
Constructs a host address object with the IPv6 address ip6Addr.
ip6Addr must be a 16-byte array in network byte order (big endian).
Constructs a host address object with the IPv6 address ip6Addr.
Constructs an IPv4 or IPv6 address using the address specified by the native structure sockaddr.
See also setAddress().
Constructs an IPv4 or IPv6 address based on the string address (e.g., "127.0.0.1").
See also setAddress().
Constructs a copy of the given address.
Constructs a QHostAddress object for address.
Destroys the host address object.
Sets the host address to 0.0.0.0.
Returns true if this host address is null (INADDR_ANY or in6addr_any). The default constructor creates a null address, and that address is not valid for any host or interface.
Returns the network layer protocol of the host address.
Returns the scope ID of an IPv6 address. For IPv4 addresses, or if the address does not contain a scope ID, an empty QString is returned.
The IPv6 scope ID specifies the scope of reachability for non-global IPv6 addresses, limiting the area in which the address can be used. All IPv6 addresses are associated with such a reachability scope. The scope ID is used to disambiguate addresses that are not guaranteed to be globally unique.
IPv6 specifies the following four levels of reachability:
When using a link-local or site-local address for IPv6 connections, you must specify the scope ID. The scope ID for a link-local address is usually the same as the interface name (e.g., "eth0", "en1") or number (e.g., "1", "2").
Эта функция была введена в Qt 4.1.
See also setScopeId().
Set the IPv4 address specified by ip4Addr.

Set the IPv6 address specified by ip6Addr.
ip6Addr must be an array of 16 bytes in network byte order (high-order byte first).

Set the IPv6 address specified by ip6Addr.
Эта перегруженная функция, предоставленная для удобства.
Sets the IPv4 or IPv6 address specified by the string representation specified by address (e.g. "127.0.0.1"). Returns true and sets the address if the address was successfully parsed; otherwise returns false.
Эта перегруженная функция, предоставленная для удобства.
Sets the IPv4 or IPv6 address specified by the native structure sockaddr. Returns true and sets the address if the address was successfully parsed; otherwise returns false.
Sets the IPv6 scope ID of the address to id. If the address protocol is not IPv6, this function does nothing.
Эта функция была введена в Qt 4.1.
See also scopeId().
Returns the IPv4 address as a number.
For example, if the address is 127.0.0.1, the returned value is 2130706433 (i.e. 0x7f000001).
This value is only valid if isIp4Addr() returns true.
Смотрите также toString().
Returns the IPv6 address as a Q_IPV6ADDR structure. The structure consists of 16 unsigned characters.
Q_IPV6ADDR addr = hostAddr.toIPv6Address(); // addr contains 16 unsigned characters for (int i = 0; i < 16; ++i) { // process addr[i] }
This value is only valid if isIPv6Address() returns true.
Смотрите также toString().
Returns the address as a string.
For example, if the address is the IPv4 address 127.0.0.1, the returned string is "127.0.0.1".
See also toIPv4Address().
Returns true if this host address is not the same as the other address given; otherwise returns false.
Эта функция была введена в Qt 4.2.
Эта перегруженная функция, предоставленная для удобства.
Returns true if this host address is not the same as the other address given; otherwise returns false.
Assigns another host address to this object, and returns a reference to this object.

Assigns the host address address to this object, and returns a reference to this object.

Returns true if this host address is the same as the other address given; otherwise returns false.
Эта перегруженная функция, предоставленная для удобства.
Returns true if this host address is the same as the other address given; otherwise returns false.
Эта перегруженная функция, предоставленная для удобства.
Writes host address address to the stream out and returns a reference to the stream.
