6       Net::DNS::Question - DNS question class
7

SYNOPSIS

9       "use Net::DNS::Question"
10

DESCRIPTION

12       A "Net::DNS::Question" object represents a record in the question
13       section of a DNS packet.
14

METHODS

16   new
17           $question = Net::DNS::Question->new("example.com", "MX", "IN");
18
19       Creates a question object from the domain, type, and class passed as
20       arguments.
21
22       RFC4291 and RFC4632 IP address/prefix notation is supported for queries
23       in in-addr.arpa and ip6.arpa subdomains.
24
25   parse
26           ($question, $offset) = Net::DNS::Question->parse(\$data, $offset);
27
28       Parses a question section record at the specified location within a DNS
29       packet.  The first argument is a reference to the packet data.  The
30       second argument is the offset within the packet where the question
31       record begins.
32
33       Returns a Net::DNS::Question object and the offset of the next location
34       in the packet.
35
36       Parsing is aborted if the question object cannot be created (e.g.,
37       corrupt or insufficient data).
38
39   qname, zname
40           print "qname = ", $question->qname, "\n";
41           print "zname = ", $question->zname, "\n";
42
43       Returns the domain name.  In dynamic update packets, this field is
44       known as "zname" and refers to the zone name.
45
46   qtype, ztype
47           print "qtype = ", $question->qtype, "\n";
48           print "ztype = ", $question->ztype, "\n";
49
50       Returns the record type.  In dymamic update packets, this field is
51       known as "ztype" and refers to the zone type (must be SOA).
52
53   qclass, zclass
54           print "qclass = ", $question->qclass, "\n";
55           print "zclass = ", $question->zclass, "\n";
56
57       Returns the record class.  In dynamic update packets, this field is
58       known as "zclass" and refers to the zone's class.
59
60   print
61           $question->print;
62
63       Prints the question record on the standard output.
64
65   string
66           print $qr->string, "\n";
67
68       Returns a string representation of the question record.
69
70   data
71           $qdata = $question->data($packet, $offset);
72
73       Returns the question record in binary format suitable for inclusion in
74       a DNS packet.
75
76       Arguments are a "Net::DNS::Packet" object and the offset within that
77       packet's data where the "Net::DNS::Question" record is to be stored.
78       This information is necessary for using compressed domain names.
