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.

       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.
