    Description

      Unlike QAbstractSocket::connectToHostImplementation does, QAbstractSocket::waitForConnected does not check whether the current host name is an ip address before doing DNS query on it. As a result, it ends up performing an unecessary and sometimes expensive reverse name lookup. Please change waitForConnected to do the same thing connectToHostImplementation does.
