Net::DNS::Question - DNS question class
Net::DNS::Question object represents a record in the question section of a DNS packet.
$question = Net::DNS::Question->new("example.com", "MX", "IN");
Creates a question object from the domain, type, and class passed as arguments.
RFC4291 and RFC4632 IP address/prefix notation is supported for queries in in-addr.arpa and ip6.arpa subdomains.
($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).
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.
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).
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.
Prints the question record on the standard output.
print $qr->string, "\n";
Returns a string representation of the question record.
$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.
