Thanks for the reply.Acording to your suggestion i have written the code as follows. 
my $QNAME= "www.google.com"; 
 
my ($QNAME1, $QNAME2,$QNAME3)= split(/\./,$QNAME);
my ($len1,$len2, $len3)=(length($QNAME1),length($QNAME2),length($QNAME
+3));

Then how to use the pack(('C',0)or "\x00") for in this case.So that it deocded the value as '0377777706676F6F676C6503636F6D00'.

Plz suggest.
