        """
        Description
            Search each Device Group's Network Group for the networkGroupIpAddress.
            If found, return the Network Group object.
            Mainly used for Traffic Item source/destination endpoints.

            The networkGroupIpAddress cannot be a range. It has to be an actual IP address
            within the range.

        Parameter
           networkGroupIpAddress: <str>: The network group IP address.

        Returns
            None: No ipAddress found in any NetworkGroup.
            network group Object: The Network Group object.
