Print out some debug information in your code, like all the hash values as they come in, that way you can see what is happening.

use Data::Dumper;

$peer_address = $client_socket->peerhost();

print "peer_address\n";

## check against previous connections
    if (exists $has{$peer_address})
    {
       
      print "exists\n";  

      $has{$peer_address}->{times_connect}++;
      print "No. of Times it has communicated : $has{$peer_address}-
+>{times_connect}";
    }
    else 
    {
        print "new connection\n";
        $t=1;
        ++$has{$peer_address};
        $has{$peer_address}->{times_connect}=$t;
    }    
    
    }

#see what you have
print $DATA::Dumper(\%has),"\n";
