.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.
\fBThis function is obsolete.\fR It is provided to keep old source working.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\fBThis function is obsolete.\fR It is provided to keep old source working.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.
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.
