Hi

There must be a better way, but this the best idea I could come up quickly from the top of my mind, and it works:

use strict;
use warnings;
my @array;

my $VAR1 = {
          '1.2.3.4' => {
                              '27029' => 5,
                              '20617' => 1 
                       },                  
          '1.2.3.5' => {                   
                              '51509' => 1,
                              '17427' => 1,
                              '63961' => 7,
                              '22331' => 1,
                              '20780' => 7 
                       },                  
          '1.2.3.6' => {                   
                              '1500' => 3  
                       },                                             
+                                                        
};

for my $var1 (keys %$VAR1) {
    push @array, [$var1, $_, $$VAR1{$var1}{$_}] for keys %{$$VAR1{$var
+1}};
}
print map {$_->[0], "\t", $_->[1], "\t", $_->[2], "times \n"} sort {$a
+->[2] <=> $b->[2]} @array;

Update This is strange, there was no answer when I posted my answer, and now it appears that two monks actually posted before me. I do not understand this and would probably have not posted the above if I has seen the prevoous answers.
