Do you need to store the answers ?

#!perl
use strict;
use warnings;
use JSON;

my %host = ();
while (<DATA>) {
  chomp;
  my @f = split /;/, $_;
  if ($f[0] eq 'Query') {
    $host{$f[1]} = $f[3];
  } elsif ($f[0] eq 'Answer') {
    my $json = encode_json { host=>$host{$f[1]},$f[2]=>$f[3] };
    print $json."\n";
    delete $host{$f[1]};
  }
}

__DATA__
Query;1;host;www.example.com
Answer;1;ip;1.2.3.4
Query;2;host;www.cnn.com
Query;3;host;www.google.com
Answer;2;ip;2.3.4.5
