Net::DNS::Question(3)                User Contributed Perl Documentation               Net::DNS::Question(3)



NAME
       Net::DNS::Question - DNS question class

SYNOPSIS
       "use Net::DNS::Question"

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

METHODS
   new
           $question = Net::DNS::Question->new("example.com", "MX", "IN");

       Creates a question object from the domain, type, and class passed as arguments.

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

   parse
           ($question, $offset) = Net::DNS::Question->parse(\$data, $offset);

       Parses a question section record at the specified location within a DNS packet.  The first argument
       is a reference to the packet data.  The second argument is the offset within the packet where the
       question record begins.

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

       Parsing is aborted if the question object cannot be created (e.g., corrupt or insufficient data).

   qname, zname
           print "qname = ", $question->qname, "\n";
           print "zname = ", $question->zname, "\n";

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

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

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

   print
           $question->print;

       Prints the question record on the standard output.

   string
           print $qr->string, "\n";

       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.
