net::dns::header
Net::DNS::Header(3) User Contributed Perl Documentation Net::DNS::Header(3)NAME
Net::DNS::Header - DNS packet header class
SYNOPSIS
"use Net::DNS::Header;"
DESCRIPTION
A "Net::DNS::Header" object represents the header portion of a DNS packet.
METHODS
new
$header = Net::DNS::Header->new;
$header = Net::DNS::Header->new($data);
Without an argument, "new" creates a header object appropriate for making a DNS query.
If "new" is passed a reference to a scalar containing DNS packet data, it creates a header object from that data.
Returns undef if unable to create a header object (e.g., if the data is incomplete).
print
$header->print;
Dumps the header data to the standard output.
string
print $header->string;
Returns a string representation of the header object.
id
print "query id = ", $header->id, "
";
$header->id(1234);
Gets or sets the query identification number.
qr
print "query response flag = ", $header->qr, "
";
$header->qr(0);
Gets or sets the query response flag.
opcode
print "query opcode = ", $header->opcode, "
";
$header->opcode("UPDATE");
Gets or sets the query opcode (the purpose of the query).
aa
print "answer is ", $header->aa ? "" : "non-", "authoritative
";
$header->aa(0);
Gets or sets the authoritative answer flag.
tc
print "packet is ", $header->tc ? "" : "not ", "truncated
";
$header->tc(0);
Gets or sets the truncated packet flag.
rd
print "recursion was ", $header->rd ? "" : "not ", "desired
";
$header->rd(0);
Gets or sets the recursion desired flag.
cd
print "checking was ", $header->cd ? "not" : "", "desired
";
$header->cd(0);
Gets or sets the checking disabled flag.
ra
print "recursion is ", $header->ra ? "" : "not ", "available
";
$header->ra(0);
Gets or sets the recursion available flag.
rcode
print "query response code = ", $header->rcode, "
";
$header->rcode("SERVFAIL");
Gets or sets the query response code (the status of the query).
qdcount, zocount
print "# of question records: ", $header->qdcount, "
";
$header->qdcount(2);
Gets or sets the number of records in the question section of the packet. In dynamic update packets, this field is known as "zocount" and
refers to the number of RRs in the zone section.
ancount, prcount
print "# of answer records: ", $header->ancount, "
";
$header->ancount(5);
Gets or sets the number of records in the answer section of the packet. In dynamic update packets, this field is known as "prcount" and
refers to the number of RRs in the prerequisite section.
nscount, upcount
print "# of authority records: ", $header->nscount, "
";
$header->nscount(2);
Gets or sets the number of records in the authority section of the packet. In dynamic update packets, this field is known as "upcount" and

";
$header->arcount(3);
