Perl accessing a hash within a hash and looping through each to extract the value

I am trying to access a hash within a hash and loop through it to get the values. here is an example of the data

$VAR1 = {
      '24.40.53.143' => {
                          'ServStat' => {
                                          '1.18.118.115.95.99.119.98.98.112.109.45.97.112.95.104.116.116.112.115' => 'vs_cgggbpm-ap_https',
                                          '1.17.118.115.95.99.119.98.115.102.97.45.97.112.95.104.116.116.112' => 'vs_cddedsfa-ap_http',
                                          '20.18.118.115.95.99.119.98.116.119.98.45.98.112.95.104.116.116.112.115' => '0',
                                          '19.17.118.115.95.99.119.98.119.115.45.97.112.95.104.116.116.112.115' => '0',
                                          '2.18.118.115.95.99.119.98.116.119.98.45.98.112.95.104.116.116.112.115' => '0',
                                          '24.18.118.115.95.99.119.98.116.119.98.45.97.112.95.104.116.116.112.115' => '0',
                         开发者_开发技巧                 '17.17.118.115.95.99.119.98.119.98.45.97.112.95.104.116.116.112.115' => '0',
                                          '29.17.118.115.95.99.119.98.116.119.112.45.98.112.95.104.116.116.112' => '0',  

I would like to loop through 'ServStat' and extract each values. How would I reference the hash 'ServStat' so that I can do a foreach on the contents? Something like this:

foreach {ServStat} {
my ( $num, $char, $vs ) = (/(\d+)\.(\d+)\.(.+)/ );
if ($num == 1) { 
print {ServStat}->$value
}
}  

Thank you in advance for any advise you can offer!

To get the keys, you can use the function keys on the hash.

my $data = {
      '24.40.53.143' => {
                          'ServStat' => {'1.18.118.115.95.99.119.98.98.112.109.45.97.112.95.104.116.116.112.115' => 'vs_cgggbpm-ap_https'}
      }
};


my $ServStat = $data->{24.40.53.143}{ServStat};

foreach my $key (keys %{$ServStat}) { # you need the {} to dereference as $ServStat is a hash reference
 ...#Now, in $key, you have the key 1.18.118.115.95.99.119.98.98.112.109.45.97.112.95.104.116.116.112.115

}  

If you just want all values, just use the function values on the hash

my @values = values %{$ServStat};
