<hr><h2><a name="details"></a>Detailed Description</h2>
The QHostAddress class provides an IP address.
<p>
This class contains an IP address in a platform- and protocol-independent
manner. That is, it'll store the address in a way you can access easily on
any platform, and it'll store both IPv4 and IPv6 addresses.
<p>QHostAddress is normally used with the classes <a href="qsocket.html">QSocket</a>, <a href="qserversocket.html">QServerSocket</a> and
<a href="qsocketdevice.html">QSocketDevice</a> to set up a server or to connect to a host.
<p>See also <a href="qsocket.html">QSocket</a>, <a href="qserversocket.html">QServerSocket</a> and <a href="qsocketdevice.html">QSocketDevice</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class="fn"><a name="bb150a"></a>QHostAddress::QHostAddress()</h3>
<p>Creates a socket address object with the IP address 0.0.0.0.
<h3 class="fn"><a name="d3d30f"></a>QHostAddress::QHostAddress(Q_UINT32ip4Addr)</h3>
<p>Creates a socket address object with a specified IPv4 address.
<h3 class="fn"><a name="2f2d6e"></a>QHostAddress::QHostAddress(Q_UINT8*ip6Addr)</h3>
<p>Creates a socket address object with a specified IPv6 address.
<p><em>ip6Addr</em> must be a 16 byte array in network byte order (high-order byte
first).
<h3 class="fn"><a name="3d54f6"></a>QHostAddress::QHostAddress(constQHostAddress&address)</h3>
<p>Creates a copy of <em>address.</em>
<h3 class="fn"><a name="907be6"></a>QHostAddress::~QHostAddress() <code>[virtual]</code></h3>
<p>Destructs the socket address object.
<h3 class="fn">Q_UINT32<a name="532c98"></a>QHostAddress::ip4Addr()const</h3>
<p>Returns the IPv4 address as a number.
<p>For example, if the address is 127.0.0.1, the returned value is
2130706433 (hex: 7f000001).
<p>This value is only valid when <a href="#914640">isIp4Addr</a>() returns TRUE.
<p>See also <a href="#256b57">toString</a>().
<h3 class="fn">bool<a name="914640"></a>QHostAddress::isIp4Addr()const</h3>
<p>Return true if the host address represents a IPv4 address.
<h3 class="fn">QHostAddress&<a name="65dab7"></a>QHostAddress::operator=(constQHostAddress&address)</h3>
<p>Assigns another socket address object <em>address</em> to this object and
returns a reference to this object.
<h3 class="fn">bool<a name="2c9253"></a>QHostAddress::operator==(constQHostAddress&other)const</h3>
<p>Returns TRUE if this socket address is identical to <em>other,</em> or FALSE
if they are different.
<h3 class="fn">bool<a name="93cdfd"></a>QHostAddress::setAddress(const<a href="qstring.html">QString</a>&address)</h3>
<p>Sets the IPv4 or IPv6 address specified by the string representation
<em>address</em> (e.g. "127.0.0.1").
<p>If this function is not able to parse the address it will return FALSE and
the address is not changed.
<h3 class="fn">void<a name="4189ce"></a>QHostAddress::setAddress(Q_UINT32ip4Addr)</h3>
<p>Set a IPv4 address specified by <em>ip4Addr.</em>
<h3 class="fn">void<a name="cbb412"></a>QHostAddress::setAddress(Q_UINT8*ip6Addr)</h3>
<p>Set a IPv6 address specified by <em>ip6Addr.</em>
<p><em>ip6Addr</em> must be a 16 byte array in network byte order (high-order byte
first).
<h3 class="fn"><a href="qstring.html">QString</a><a name="256b57"></a>QHostAddress::toString()const</h3>
<p>Returns the address as a string.
<p>For example, if the address is the IPv4 address 127.0.0.1, the
returned string is "127.0.0.1".
<p>See also <a href="#532c98">ip4Addr</a>().
