-    \class QDnsLookup
-    \brief The QDnsLookup class represents a DNS lookup.
-
-    \inmodule QtNetwork
-    \ingroup network
-
-    QDnsLookup uses the mechanisms provided by the operating system to perform
-    DNS lookups. To perform a lookup you need to specify a \l name and \l type
-    then invoke the \l{QDnsLookup::lookup()}{lookup()} slot. The
-    \l{QDnsLookup::finished()}{finished()} signal will be emitted upon
-    completion.
-
-    For example, you can determine which servers an XMPP chat client should
-    connect to for a given domain with:
-
-    \snippet doc/src/snippets/code/src_network_kernel_qdnslookup.cpp 0
-
-    Once the request finishes you can handle the results with:
-
-    \snippet doc/src/snippets/code/src_network_kernel_qdnslookup.cpp 1
-
-    \note If you simply want to find the IP address(es) associated with a host
-    name, or the host name associated with an IP address you should use
-    QHostInfo instead.
