";
	   print "zname = ", $question->zname, "
";

       Returns the domain name.  In dynamic update packets, this field is known as "zname" and refers to the zone name.

       qtype, ztype

	   print "qtype = ", $question->qtype, "
";
	   print "ztype = ", $question->ztype, "
";

       Returns the record type.  In dymamic update packets, this field is known as "ztype" and refers to the zone type (must be SOA).

       qclass, zclass

	   print "qclass = ", $question->qclass, "
";
	   print "zclass = ", $question->zclass, "
";

       Returns the record class.  In dynamic update packets, this field is known as "zclass" and refers to the zone's class.

       print

       Prints the question record on the standard output.

       string

	   print $qr->string, "
";

       Returns a string representation of the question record.

       data

	   $qdata = $question->data($packet, $offset);

       Returns the question record in binary format suitable for inclusion in a DNS packet.

       Arguments are a "Net::DNS::Packet" object and the offset within that packet's data where the "Net::DNS::Question" record is to be stored.
       This information is necessary for using compressed domain names.
