If you really need the 'ip address', you can use the right expression. 
use Regexp::Common qw/net/;                                           
+                         
my $ip_regexp = qr($RE{net {IPv4});                                   
+                          
while(<DATA>)  {                                                      
+                                        
  if (/($ip_regexp)/)  {                                              
+                                               
   my $ip_address = $1;                                               
+                            
    print "$ip_address\n";                                            
+                          
 }                                                                    
+                         
}
