DESCRIPTION
       The QHostAddress class provides an IP address.

       This class contains an IP address in a platform and protocol independent manner. It stores
       both IPv4 and IPv6 addresses in a way that you can easily access on any platform.

       QHostAddress is normally used with the classes QSocket, QServerSocket and QSocketDevice to
       set up a server or to connect to a host.

       Host addresses may be set with setAddress() and retrieved with ip4Addr() or toString().

       See also QSocket, QServerSocket, QSocketDevice, and Input/Output and Networking.

MEMBER FUNCTION DOCUMENTATION
QHostAddress::QHostAddress ()
       Creates a host address object with the IP address 0.0.0.0.

QHostAddress::QHostAddress ( Q_UINT32 ip4Addr )
       Creates a host address object for the IPv4 address ip4Addr.

QHostAddress::QHostAddress ( Q_UINT8 * ip6Addr )
       Creates a host address object with the specified IPv6 address.

       ip6Addr must be a 16 byte array in network byte order (high-order byte first).

QHostAddress::QHostAddress ( const Q_IPV6ADDR & ip6Addr )
       Creates a host address object with the IPv6 address, ip6Addr.

QHostAddress::QHostAddress ( const QHostAddress & address )
       Creates a copy of address.

QHostAddress::~QHostAddress () [virtual]
       Destroys the host address object.

Q_UINT32 QHostAddress::ip4Addr () const
       This function is obsolete. It is provided to keep old source working. We strongly advise
       against using it in new code.

       Use toIPv4Address() instead.

bool QHostAddress::isIPv4Address () const
       Returns TRUE if the host address represents an IPv4 address; otherwise returns FALSE.

bool QHostAddress::isIPv6Address () const
       Returns TRUE if the host address represents an IPv6 address; otherwise returns FALSE.

bool QHostAddress::isIp4Addr () const
       This function is obsolete. It is provided to keep old source working. We strongly advise
       against using it in new code.

       Use isIPv4Address() instead.

bool QHostAddress::isNull () const
       Returns TRUE if this host address is null (INADDR_ANY or in6addr_any). The default
       constructor creates a null address, and that address isn't valid for any particular host
       or interface.

QHostAddress &; QHostAddress::operator= ( const QHostAddress & address )
       Assigns another host address object address to this object and returns a reference to this
       object.

bool QHostAddress::operator== ( const QHostAddress & other ) const
       Returns TRUE if this host address is the same as other; otherwise returns FALSE.

void QHostAddress::setAddress ( Q_UINT32 ip4Addr )
       Set the IPv4 address specified by ip4Addr.

void QHostAddress::setAddress ( Q_UINT8 * ip6Addr )
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Set the IPv6 address specified by ip6Addr.

       ip6Addr must be a 16 byte array in network byte order (high-order byte first).

bool QHostAddress::setAddress ( const QString & address )
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Sets the IPv4 or IPv6 address specified by the string representation address (e.g.
       "127.0.0.1"). Returns TRUE and sets the address if the address was successfully parsed;
       otherwise returns FALSE and leaves the address unchanged.

Q_UINT32 QHostAddress::toIPv4Address () const
       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 when isIp4Addr() returns TRUE.

       See also toString().

Q_IPV6ADDR QHostAddress::toIPv6Address () const
       Returns the IPv6 address as a Q_IPV6ADDR structure. The structure consists of 16 unsigned
       characters.

	       Q_IPV6ADDR addr = hostAddr.ip6Addr();
	       // addr.c[] contains 16 unsigned characters
	       for (int i = 0; i < 16; ++i) {
		   // process addr.c[i]
	       }

       This value is only valid when isIPv6Address() returns TRUE.

       See also toString().

QString QHostAddress::toString () const
       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 ip4Addr().
