162 QDnsLookup uses the mechanisms provided by the operating system to perform-
163 DNS lookups. To perform a lookup you need to specify a \l name and \l type-
164 then invoke the \l{QDnsLookup::lookup()}{lookup()} slot. The-
165 \l{QDnsLookup::finished()}{finished()} signal will be emitted upon-
166 completion.-

168 For example, you can determine which servers an XMPP chat client should-
169 connect to for a given domain with:-

171 \snippet code/src_network_kernel_qdnslookup.cpp 0-

173 Once the request finishes you can handle the results with:-
