+.SH DESCRIPTION
+The QHostAddress class provides an IP address.
+.PP
+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.
+.PP
+QHostAddress is normally used with the classes QSocket, QServerSocket and QSocketDevice to set up a server or to connect to a host.
+.PP
+Host addresses may be set with setAddress() and retrieved with ip4Addr() or toString().
+.PP
+See also QSocket, QServerSocket, QSocketDevice, and Input/Output and Networking.
+.SH MEMBER FUNCTION DOCUMENTATION
+.SH "QHostAddress::QHostAddress ()"
+Creates a host address object with the IP address 0.0.0.0.
+.SH "QHostAddress::QHostAddress ( Q_UINT32 ip4Addr )"
+Creates a host address object for the IPv4 address \fIip4Addr\fR.
+.SH "QHostAddress::QHostAddress ( Q_UINT8 * ip6Addr )"
+Creates a host address object with the specified IPv6 address.
+.PP
+\fIip6Addr\fR must be a 16 byte array in network byte order (high-order byte first).
+.SH "QHostAddress::QHostAddress ( const Q_IPV6ADDR & ip6Addr )"
+Creates a host address object with the IPv6 address, \fIip6Addr\fR.
+.SH "QHostAddress::QHostAddress ( const QHostAddress & address )"
+Creates a copy of \fIaddress\fR.
+.SH "QHostAddress::~QHostAddress ()\fC [virtual]\fR"
+Destroys the host address object.
+.SH "Q_UINT32 QHostAddress::ip4Addr () const"
+\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
+.PP
+Use toIPv4Address() instead.
+.SH "bool QHostAddress::isIPv4Address () const"
+Returns TRUE if the host address represents an IPv4 address; otherwise returns FALSE.
+.SH "bool QHostAddress::isIPv6Address () const"
+Returns TRUE if the host address represents an IPv6 address; otherwise returns FALSE.
+.SH "bool QHostAddress::isIp4Addr () const"
+\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
+.PP
+Use isIPv4Address() instead.
+.SH "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.
+.SH "QHostAddress & QHostAddress::operator= ( const QHostAddress & address )"
+Assigns another host address object \fIaddress\fR to this object and returns a reference to this object.
+.SH "bool QHostAddress::operator== ( const QHostAddress & other ) const"
+Returns TRUE if this host address is the same as \fIother\fR; otherwise returns FALSE.
+.SH "void QHostAddress::setAddress ( Q_UINT32 ip4Addr )"
+Set the IPv4 address specified by \fIip4Addr\fR.
+.SH "void QHostAddress::setAddress ( Q_UINT8 * ip6Addr )"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Set the IPv6 address specified by \fIip6Addr\fR.
+.PP
+\fIip6Addr\fR must be a 16 byte array in network byte order (high-order byte first).
+.SH "bool QHostAddress::setAddress ( const QString & address )"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Sets the IPv4 or IPv6 address specified by the string representation \fIaddress\fR (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.
+.SH "Q_UINT32 QHostAddress::toIPv4Address () const"
+Returns the IPv4 address as a number.
+.PP
+For example, if the address is 127.0.0.1, the returned value is 2130706433 (i.e. 0x7f000001).
+.PP
+This value is only valid when isIp4Addr() returns TRUE.
+.PP
+See also toString().
+.SH "Q_IPV6ADDR QHostAddress::toIPv6Address () const"
+Returns the IPv6 address as a Q_IPV6ADDR structure. The structure consists of 16 unsigned characters.
+.PP
+.nf
+.br
+ Q_IPV6ADDR addr = hostAddr.ip6Addr();
+.br
+ // addr.c[] contains 16 unsigned characters
+.br
+.br
+ for (int i = 0; i < 16; ++i) {
+.br
+ // process addr.c[i]
+.br
+ }
+.br
+.fi
+.PP
+This value is only valid when isIPv6Address() returns TRUE.
+.PP
+See also toString().
+.SH "QString QHostAddress::toString () const"
+Returns the address as a string.
+.PP
+For example, if the address is the IPv4 address 127.0.0.1, the returned string is "127.0.0.1".
+.PP
+See also ip4Addr().
