Net::DNS::Question(3pmUser Contributed Perl DocumentatiNet::DNS::Question(3pm)

NAME
       Net::DNS::Question - DNS question record

SYNOPSIS
	   use Net::DNS::Question;

	   $question = new Net::DNS::Question('example.com', 'A', 'IN');

DESCRIPTION
       A Net::DNS::Question object represents a record in the question section
       of a DNS packet.

METHODS
   new
	   $question = new Net::DNS::Question('example.com', 'A', 'IN');
	   $question = new Net::DNS::Question('example.com');

	   $question = new Net::DNS::Question('192.0.32.10', 'PTR', 'IN');
	   $question = new Net::DNS::Question('192.0.32.10');

       Creates a question object from the domain, type, and class passed as
       arguments. One or both type and class arguments may be omitted and will
       assume the default values shown above.

       RFC4291 and RFC4632 IP address/prefix notation is supported for queries
       in both in-addr.arpa and ip6.arpa namespaces.

   decode
	   $question = decode Net::DNS::Question(\$data, $offset);

	   ($question, $offset) = decode Net::DNS::Question(\$data, $offset);

       Decodes the question record at the specified location within a DNS
       wire-format packet.  The first argument is a reference to the buffer
       containing the packet data.  The second argument is the offset of the
       start of the question record.

       Returns a Net::DNS::Question object and the offset of the next location
       in the packet.

       An exception is raised if the object cannot be created (e.g., corrupt
       or insufficient data).

   encode
	   $data = $question->encode( $offset, $hash );

       Returns the Net::DNS::Question in binary format suitable for inclusion
       in a DNS packet buffer.

       The optional arguments are the offset within the packet data where the
       Net::DNS::Question is to be stored and a reference to a hash table used
       to index compressed names within the packet.

   qname, zname
	   $qname = $question->qname;
	   $zname = $question->zname;

       Returns the question name attribute.  In dynamic update packets, this
       attribute is known as zname() and refers to the zone name.

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

       Returns the question type attribute.  In dynamic update packets, this
       attribute is known as ztype() and refers to the zone type.

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

       Returns the question class attribute.  In dynamic update packets, this
       attribute is known as zclass() and refers to the zone class.

   print
	   $object->print;

       Prints the record to the standard output.  Calls the string() method to
       get the string representation.

   string
	   print "string = ", $question->string, "\n";

       Returns a string representation of the question record.
