Hello Everyone! Another Question, when we send the DNS packet, how does its query format look like, i mean does it look like e.g "3www6google3com011" or like "wwwgooglecom011"? Please help! when i send a packet, in wireshark, it shows the Query name like "3.www.6.google.3.com"! any one know y?? i packed it like this (as suggested by others): 
my $hostname = $ARGV[0];

my @labels;
my $nlabels = 0;

for (split /\./, $hostname) {
    push @labels, length, $_;
    $nlabels++;
}

my $n = scalar(@labels);

my $question = pack("(C/a*)$n C n2", @labels, 0, 1, 1) ;

or used this one: 
 my @labels = split(/\./, $hostname) ; 
my $n = scalar(@labels) ; 
my $question = pack("(C/a*)$n C n2", @labels, 0, 1, 1) ;
